These machines are constructed for maximum operator safety when used under standard
operating conditions and when recommended instructions are followed in the maintenance
and operation of the machine.
All personnel engaged in the use of the machine should become familiar with its operation as
described in this manual.
Proper operation of the machine promotes safety for the operator and all workers in its
vicinity.
Each individual must take responsibility for observing the prescribed safety rules as outlined.
All warning and danger signs must be observed and obeyed. All actual or potential danger
areas must be reported to your immediate supervisor.
General Responsibility
No matter who you are, safety is important. Owners, operators and maintenance personnel
must realize that every day, safety is a vital part of their jobs.
If your main concern is loss of productivity, remember that production is always affected in a
negative way following an accident. The following are some of the ways that accidents can
affect your production:
• Loss of a skilled operator (temporarily or permanently)
• Breakdown of shop morale
• Costly damage to equipment
• Downtime
An effective safety program is responsible and economically sound.
Organize a safety committee or group, and hold regular meetings. Promote this group from
the management level. Through this group, the safety program can be continually reviewed,
maintained, and improved. Keep minutes or a record of the meetings.
Hold daily equipment inspections in addition to regular maintenance checks. You will keep
your equipment safe for production and exhibit your commitment to safety.

Operator Responsibility
The operator’s responsibility does not end with efficient production. The operator usually has
the most daily contact with the equipment and intimately knows its capabilities and
limitations.
Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or
through a casual attitude toward machinery formed over a period of months or years. Your
employer probably has established a set of safety rules in your workplace. Those rules, this
manual, or any other safety information will not keep you from being injured while operating
your equipment.
Learn and always use safe operation procedures. Cooperate with co-workers to promote safe
practices. Immediately report any potentially dangerous situation to your supervisor or
appropriate person.
REMEMBER:
• NEVER place your hands or any part of your body in any dangerous location.
• NEVER operate, service, or adjust the feeder without appropriate training and first
reading and understanding this manual.
• NEVER try to pull material out of the feeder with your hands while it is running!
• Before you start the feeder check the following:
• Remove all tools from the feeder;
• Be sure no objects (tools, nuts, bolts, clamps, bars) are laying in the
hopper area;
• If your feeder has been inoperative or unattended, check all settings before starting the
unit.
• At the beginning of your shift and after breaks, verify that the controls and other
auxiliary equipment are functioning properly.
• Keep all safety guards in place and in good repair. NEVER attempt to bypass, modify,
or remove safety guards. Such alteration is not only unsafe, but will void the warranty
on your equipment.
• When changing control settings to perform a different mode of operation, be sure
selector switches are correctly positioned. Locking selector switches should only be
adjusted by authorized personnel and the keys removed after setting.
• Report the following occurrences IMMEDIATELY:
• unsafe operation or condition
• unusual feeder action
• leakage
• improper maintenance
• NEVER stand or sit where you could slip or stumble into the feeder
while working on it.
• DO NOT wear loose clothing or jewelry, which can be caught while working on a
feeder. In addition, cover or tie back long hair.

Safety Circuit Standards
Safety circuits used in industrial systems protect the operator and maintenance personnel
from dangerous energy. They also provide a means of locking out or isolating the energy for
servicing equipment.
Various agencies have contributed to the establishment of safety standards that apply to the
design and manufacture of automated equipment. The Occupational Safety and Health
Administration (OSHA) and the Joint Industrial council (JIC) are just a few of the
organizations that have joined with the plastics industry to develop safety standards.
Every effort has been made to incorporate these standards into the design of the additive
feeder; however, it is the responsibility of the personnel operating and maintaining the
equipment to familiarize themselves with the safety procedures and the proper use of any
safety devices.
Fail Safe Operation
If a safety device or circuit should fail, the design must be such that the failure causes a
“Safe” condition. As an example, a safety switch must be a normally open switch. The switch
must be held closed with the device it is to protect. If the switch fails, it will go to the open
condition, tripping out the safety circuit.
At no time should the safety device fail and allow the operation to continue. For
example, if a safety switch is guarding a motor, and the safety switch fails, the motor should
not be able to run.
Safety Device Lock-Outs
Some safety devices disconnect electrical energy from a circuit. The safety devices that are
used on these additive feeders are primarily concerned with electrical power disconnection
and the disabling of moving parts that may need to be accessed during the normal operation
of the machine.
Some of the safety devices utilize a manual activator. This is the method of initiating the
safety lock out. This may be in the form of a plug, lever or a handle. Within this lockable
handle, there may be a location for a padlock. Personnel servicing the equipment should
place a padlock in the lockout handle.
In addition to the safety devices listed above, these additive feeders are equipped with a line
cord plug. This allows the operator or maintenance personnel to unplug the additive feeder
from its power source and tag it out. The plug can then be tagged with any number of
approved electrical lockout tags available at most electrical supply stores.
WARNING! Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air)
sources prior to servicing or cleaning the additive feeder. Failure to do so may result in
serious injury. No one but the person who installed the lockout may remove it.

2. Use a pry bar to remove the blocks securing the unit to the skid.
3. Lift unit from sides. Use a pry bar if necessary to carefully remove the skid
from the unit.
3-2 Rigging and Placing the Additive Feeder
Note: Disassemble the material transport assembly from the main throat to
ease marking, drilling and installation of the additive feeder.
If the machine throat is smaller than the additive feeder throat,
adapters are available.
1. Remove hopper from your processing machine.
2. Drill holes in both flanges of the additive feeder main throat to exactly match
the bolt hole pattern on your processing machine throat. Select a position for
easy operator access.
3. Bolt the main throat to the machine, and the machine hopper to the main throat
with the appropriate bolts, nuts and lockwashers.
4. Mount the control in a position with convenient operator access near the
additive feeder. Avoid locations with excessive dust, vibration and moisture.
Supply System Installation
If the additive feeder is to be used with an automatic loading system, install the hopper
loader, vacuum hopper, etc., in the supply hopper cover. Follow the instructions provided
with the loading system.

3-3 Electrical Connections
When making electrical connections to your additive feeder, ensure that you take into
consideration and make arrangements for the following:
• A qualified electrician should make all electrical connections.
• Fulfill all national, state, and local safety and electrical code requirements.
• The serial tag lists voltage, phase, and amp draw information
• Line voltage must be within plus or minus ten percent (±10%) of the voltage listed on
the serial tag, or damage may occur.
• Install a fused disconnect with a lockout feature in the power main leading to the
additive feeder if the unit will be wired directly to a power main.
• Make sure all electrical connections are tight.
Main Power Connection
The control is shipped pre-wired and attached to the additive feeder. Standard controls are
supplied with a power cord with the plug wired to the control unit, ready to plug into an
appropriately grounded three-prong receptacle.
Control Relay Connection
To interlock the additive feeder operation to an injection molding machine, extruder, etc.,
remove jumper (J1) from the terminal block in the control enclosure and wire in the control
relay signal from the processing machine. For injection applications the additive feeder will
automatically operate at the specified rate while the screw is turning.(see 4-3, Injection Mode
Application), for extrusion processes the additive feeder will run proportional to the speed of
the extruder. (See 4-4, Extrusion Mode Application)
Please refer to the schematics enclosed in the information packet for the latest electrical
drawings.

3-4 Setup Procedures
This section provides the procedures necessary for configuring your additive feeder.
Configuration of your additive feeder includes determining the desired feed rate and
calibrating the additive feeder. We recommend that you carry out these procedures in the
order given here.
Note: Before carrying out these procedures, install all equipment as
described in this section.
Determining the Desired Feed Rate
The additive feed rate is the desired amount of additive to be introduced into the process
stream per hour. To determine the feed rate, follow the procedure in this section. If the
desired feed rate is known, go to the calibration procedure in the next section. The charts in
figures 1 and 2 on the following page provide conversion and rate charts to assist you in your
calculations.
For Cyclical Processing (Injection Molding, etc.)
To set up an additive feeder for cyclical processing, you need to know shot size, recovery
time, and the letdown ratio.
Cyclical Processing Equation:
Shot Size (oz)
Recovery time (sec) x Letdown (ratio or %) x 225 = Feed Rate (lbs./hr.)
Example:
Shot size = 8 ounces
Recovery time = 5 seconds
Letdown ratio = 20:1
8 oz./5 sec. X 1/20 = 0.08 = Desired feed rate
To convert to lbs./hr.: 0.08 oz/sec x 225 = 18 lbs./hr.
For Continuous Processing (Extrusion, etc.)
To set up an additive feeder for continuous processing, you need to know the total process
throughput and the desired additive percentage or letdown ratio.
Continuous Processing Equation:
Total throughput (lbs./hr.) x percentage of additive = Feed rate
Example:
Total throughput = 100 pounds per hour
Percentage of additive = 2%
100 lbs./hr. x 0.02 = 2 lbs./hr. feed rate

Calibration Procedure
This procedure allows the operator to precisely adjust additive feed rates.
Caution!
Never put hands or tools in or near the auger assembly when power is
connected.
Do not wear gloves or loose clothing during calibration. The auger is
exposed when the calibration or cleanout hatches are open.
Equipment Needed:
• Scale
• Sample container
• Timer- stopwatch, watch/clock w/second hand
Procedure
1. Close cleanout and calibration hatches.
2. Fill the additive supply hopper.
3. Weigh the empty sample container.
4. Swing open the calibration hatch near the main throat.
5. Set the controller to a desired RPM.
6. Place the sample container below the calibration hatch.
7. Hold the three-position motor switch in the Manual position for about a minute.
This lets the new setpoint stabilize and fills the auger flights with material. Discard
the first sample.
8. Position the empty scale container below the calibration hatch and hold the three-
position motor switch in the Manual position for exactly one minute.
Note: If your additive feeder is equipped with the timer option, set the timer to
one minute and put the three-position switch in the Manual position.
Operation will automatically stop after one minute.
9. Weigh the sample container. Subtract the weight of the container and multiply by
60 to determine the pounds per hour feed rate.
10. Adjust the auger rpm and repeat the calibration process until the desired feed rate is
achieved.
Note: To speed the calibration procedure, reduce trial and error auger rpm
settings and zero in on the desired feed rate. Chart the calculated feed
rates from a few rpm settings on graph paper. Draw a straight line
between the coordinates to establish a customized feed rate curve for
the actual operating conditions. A sample graph is provided on the
next page; graph paper is included in the back of this manual for use
with your feeding processes.

4-3 Injection Molding Applications
Discussed in this portion of the manual are the finer points of the additive feeder operation,
programming the control, and installation notes and examples. If you are unfamiliar with this
product or have never performed this type of installation, please read this section of the
manual fully before installing the equipment.
Steps that must be completed before the additive feeder will perform properly:
–
–
The proper control signal from the injection process
Accurate programming of the control (Factory default programming is sufficient for most
injection applications)
Injection Molding
Injection Molding cycles require that the additive feeder supply a constant feed rate during
recovery and no material during the shot. Once a desired feed rate has been identified (See 3-
4, Determining the Desired Feed Rate) and a calibration has been performed (See 3-4,
Calibration Procedure), then the correct RPM can be set for that process. Finally the additive
feeder needs to be told when to start and stop feeding material using a control connection.
Control Relay Connection
To interlock the additive feeder operation to an injection molding machine, remove jumper
(J1) from the terminal block in the control enclosure and wire in the control relay signal from
the processing machine. For injection applications the additive feeder will automatically
operate at the specified rate while the screw is turning.(see 4-3, Injection Mode Application)
Field Control Programming
Although the drive’s user interface is very versatile, it is also simple to setup and operate.
With just a few button presses, it allows the user to configure a number of adjustable
parameters. The LED display has three basic operating modes: Running Mode, Parameter-
Selection Mode, and Value Mode. Each of the three modes have specific visual indicators
that allow the user to immediately determine the current state or mode of the user interface.
Note: Parameter-Selection Mode and Value Mode can only be entered if the Program
Enable jumper is in the “On” position.
Running Mode is the default display of the unit when power is applied. The drive will spend
the majority of its time in this mode. In Running Mode, the display shows the target value in
the appropriate user defined format of rate, time, or percentage. The control will
continuously attempt to drive the motor at the requested target rate. In this display mode, the
Up and Down buttons increase or decrease the displayed target value until either the display
minimum or display maximum limit is reached. Depending on the alarm configuration, these
buttons may also serve as an alarm-silence or alarm-reset button.
Parameter-Selection Mode can be entered by simply pressing and holding the Enter button
down for three seconds. Once in Parameter-Selection Mode, the far left of the display will be
a “P.” The right side of the display will indicate the currently selected parameter number for
Additive Feeders

editing purposes. Pressing the Up or Down button will increase or decrease the selected
parameter number on the display. Although the parameter numbers are in numerical order,
some numbers are skipped. These numbers represent reserved parameters that are not yet
implemented and are not displayed. Once the desired parameter number is displayed, a press
of the Enter button will change the display to the Value Mode.
Note: When in Parameter-Selection Mode, pressing the Enter button with parameter
0 selected will cause the unit to return to Running Mode.
Value Mode is used to modify the value of the selected parameter. When in Value Mode, the
two dots which form the colon, between digits two and three, will alternately flash (one, then
the other) to inform the user that a parameter’s value is being edited. Pressing the Up or
Down button increases or decreases the selected parameter’s value. See the default value
tables (below) for the list of preprogrammed values. Value changes take effect immediately.
Once the desired value is showing in the display window, pressing the Enter button again will
return to Parameter Selection Mode. The new value is not saved in permanent memory until
the Enter button is pressed. Removing power from the unit while in Value Mode may result
in the specified new value being lost.
Resetting the Unit to Un-Programmed State
The factory-default settings can be easily restored using either of two methods. Both
methods require the Program Enable jumper to be in the “On” position. The first is to apply
power to the unit with both the Enter and Down buttons pressed for 3 seconds. The second is
to change the value of parameter 95 to 5.
JP1 (Program Enable Jumper)
The JP1 jumper is located under the dust cover on the back end of the upper board. When the
jumper is set to the "Off" position, all programming features are locked out to the front panel
user. When the jumper is in the "On" position, the programming parameters are open to
change. JP1 is shipped in the "Off" position.
Programming Step by Step Guide
1. Remove the power source from the controller. Following the procedures in
your facility, lockout or tagout the power source.
2. Remove the cover from the control enclosure
3. At the connection end of the drive lift the black plastic dust cover up slightly

feeder. If you do not have these drawings contact service to have them forwarded to
you.
Injection Mode Application Notes
The additive feeder controller has the ability to display feed rates in units other than the
factory set auger RPM display. With proper programming, the feeder can display
pounds/hour, grams/minute, etc.
Programming for units other than auger RPM REQUIRES that the system be calibrated to
determine exactly how much material is delivered at specific RPMs. Please refer to the
Calibration Procedure section for additional details.
Please note that custom programming for units other RPM will only provide meaningful
results when the auger and sleeve size does not change, and when the materials to be fed have
similar physical characteristics.
Example 1: The unit is programmed by the end user to display feed rates in pounds/hour
with a ¾” auger and sleeve. Someone else replaces this auger and sleeve with a 1” diameter
unit and does not calibrate and reprogram the controller. The displayed values are no longer
valid.
Example 2: The unit is programmed by the end user to display feed rates in pounds/hour of
a pelletized colorant material. The pellets are of a uniform size and shape, freely flow, and
contain no extraneous materials. At some point the additive feeder is used to introduce
regrind material instead of the previous colorant pellets and does not calibrate and reprogram
the controller. The displayed values are no longer valid.
When the controller is to be programmed to display in units other than auger RPM,
parameters P20, P21, and P30 will need to be modified.
The value in parameter P20 must be programmed to the lowest desired delivery rate. The
value in parameter P21 must be programmed to the highest desired delivery rate, and the
value in parameter P30 must be programmed to a value that matches what the auger delivers
when it is operating at full speed (71 RPM).
Example 1: An end user wants the additive feeder to display how many ounces per second
are delivered rather than what speed the auger is to turn at. When the end user calibrated the
unit they determined that at 10 RPM the unit delivered 1 ounce per second, and at 71 RPM
the unit delivered 7.1 ounces per second. The end user wants to be able to set the control to
deliver between 2 and 5 ounces per second. The value in parameter P20 gets programmed to
“20” which will allow a minimum setpoint of 2.0. The value in parameter P21 gets
programmed to “50” which will allow a maximum setpoint of 5.0. The value in parameter
P31 gets programmed to “71” which is how much material is delivered when the unit is
rotating at full speed (71 RPM).

4-4 Extrusion Applications
Discussed in this portion of the manual are the finer points of the additive feeder operation,
programming the control, and installation notes and examples. If you are unfamiliar with this
product or have never performed this type of installation, please read this section of the
manual fully before installing the equipment.
Steps that must be completed before the additive feeder will perform properly:
-The proper control signal from the extrusion process
-Accurate programming of the control
Extruder Tracking Control
The extruder tracking control option allows the additive feeder’s auger (follower) to turn in a
precise ratio to the speed of your extruder screw (master). The speed control on the feeder
can be set for any feed ratio from 10% to 200%.
The extruder tracking control detects the speed of the extruder screw and causes the feeder
screw to rotate at the desired RPM. In effect, the extruder tracking control acts as an
automatic speed control.
The extruder tracking control requires a 5 VDC TTL NPN RPM signal from the extruder.
Use an existing RPM signal from the extruder; consult with the extruder’s manufacturer for
the signal type and frequency.
You will need to know:
1. The signal voltage
2. The number of pulses per extruder screw revolution
A wide variety of sensors can be supplied by the manufacturer to suit your needs if the
extruder control circuit does not provide a suitable signal.
These sensors include:
• Inductive proximity sensors to sense gear teeth.
• Magnetic pickups to sense affixed magnets.
• Optic sensors to sense affixed reflective tape. (Included with extrusion tracking
control)
Consult your sales representative for additional information.
Control Relay Connection
To interlock the additive feeder operation to an extruder, remove jumper (J1) from the
terminal block in the control enclosure and wire in the control relay signal from the
processing machine. Connecting the additive feeder to the control relay simply ensures that
when the extrusion process stops so does the additive feeder. (Without this control
connection, the auger may continue feeding material for a short time).

Extruder Tracking Installation and Setup
The additive feeder control is supplied with standard factory defaults. Control programming
is required to suit the requirements of your process (See page 24, Field Control
Programming).
Connect the TTL signal acquired from the extruder control or from a sensor you have
installed to the terminal strip as shown in the electrical schematics provided with your unit’s
installation packet.
1. Install the feeder as described in Chapter 3.
2. Calibrate the feeder as described on Page 18. Determine the feed rates at different
rpms. We recommend that you plot the feed rates on graph paper.
3. Calculate a new display constant taking the extruder screw signal into account.
Constant = 1000 x # of Pulses per Revolution of Extruder Screw ℵ
# of Pulses per Revolution of the Feeder Screw ℑ
ℵ If not counted directly from screw, multiply by a “fudge factor” to get the pulses per
extruder screw rpm.
ℑ Factory set at 843 (PPR x 28.1 gear ratio).
Program the control to the new constant, as described in the next section “Field Control
Programming.”
Determine the desired additive feeder setpoint (% of extruder (master) screw RPM). To
determine this, you must know:
• Total extruder feedrate (lbs./hr.).
• The RPM of the extruder screw at that feedrate.
• The letdown ratio of the additive (% or :).
• The additive feedrate required at that letdown ratio (total feedrate X
letdown ratio).
• The additive feedrate RPM needed to achieve this feedrate (as
determined by the calibration procedure).
Extruder Tracking Equation:
Set Point = (rpm of feeder / rpm of extruder) x 100
Example:
Total extruder feedrate = 500 pounds per hour
Extruder screw rpm for 500 lbs/hr = 50 rpm
Additive letdown percentage = 7%
Additive feedrate = 500 X 0.07 = 35 lbs./hr.
Feeder auger rpm needed for 35 lbs./hr. = 44 rpm (as the calibration procedure has
shown)
Assuming this, set point = 44 rpm/50 rpm x 100 = 88 or 88% of the extruder screw speed.

feeder. If you do not have these drawings contact service to have them forwarded to
you.
Parameter # 37 requires the installer to program the correct pulses per revolution from
the extrusion machine.(See Chapter 5)
Extruder Tracking Control Application Notes
Input Pulse Signal Requirements
The drive uses a 5 volt DC square wave (TTL NPN type RPM signal) on its S2 input terminal
as a reference signal from the extruder. Please contact us for application assistance if your
extruder is not equipped with a method to provide this signal.
Minimum Input Pulse Rate
Extruder Tracking units are programmed to follow an extruder that provides eight pulses per
revolution. Additive Feeders used in extruder tracking systems REQUIRE end user
programming to match the master rate signal from the extruder’s screw if the signal
does NOT provide eight pulses per revolution. The value programmed into parameter P37
must be set to match the number of pulses per revolution that the extruder generates.
In addition, the drive must be provided a MINIMUM of 240 pulses per minute to provide
accurate results.
Additive Feeders
Chapter 4: Operation
32 of 55
Download from Www.Somanuals.com. All Manuals Search And Download.
Example 1: An extruder rotating at 30 RPM and providing 8 pulses per revolution generates
240 pulses per minute will provide excellent results.
Example 2: An extruder rotating at 15 RPM and providing 1 pulse per revolution generates
15 pulses per minute and will provide poor results.
Maximum Input Pulse Rate
As programmed, the drive is capable of accurately following an extruder’s rate signal of up to
50,000 pulses per minute. Extruders that provide rate signals above this frequency
REQUIRE end user programming to provide accurate results. The value programmed into
parameter P16 must be modified to a value that filters this pulse rate to an acceptable
frequency. Please refer to the parameter description section for additional information.
Example 1: An extruder rotating at 175 RPM and providing 8 pulses per revolution
generates 1,400 pulses per minute will provide excellent results.
Example 2: An extruder rotating at 250 RPM and providing 250 pulses per revolution
generates 62,500 pulses per minute and will provide poor results.
Minimum and Maximum Percent Setpoints
The drive rotates the additive feeder’s auger at a constant percentage of the extruder screw. If
the extruder screw is turning at 100 RPM and the setpoint is 50%, the additive feeder turns at
50 RPM. Increasing the extruder speed to 110 RPM will make the additive feeder rotate at
55 RPM. Decreasing the extruder speed to 90 RPM will make the additive feeder rotate at 45
RPM.
As programmed, the drive accepts percentage setpoints from 10% to 200% of the extruder’s
speed. The drive and motor’s acceptable operating speed range is 3 to 71 RPM.
Increasing the percent setpoint to a value that would cause the auger to rotate over 71 RPM
will NOT cause the feeder’s auger to rotate OVER 71 RPM.
Example 1: The extruder is rotating at 75 RPM, and the additive feeder percent setpoint is
85%. The additive feeder’s auger will rotate at 63.75 RPM.
Example 2: The same extruder’s speed setpoint is increased to 100 RPM without changing
the additive feeder percent setpoint of 85%. The additive feeder will rotate at its maximum
speed of 71 RPM, not at 85 RPM. If your application requires that additives be fed at a
higher rate than what71 RPM provides the simplest method is to increase the size of the
auger and sleeve your additive feeder is equipped with. Please refer to the parts section for a
complete listing of available sizes.
The minimum and maximum percent setpoints may be custom programmed to more precisely
reflect the range of speeds in use at your facility. Please refer to the parameter description
section for additional information.

Chapter 5: Program Parameter Descriptions
5-1 Defining Program Parameters
Parameter 0 – Exit to Running Mode
When parameter 0 is selected in Parameter-Selection Mode, the unit will return to Running
Mode and display the running value. This should be selected once changes to parameters are
completed.
Parameter 10 – Operating Mode
This parameter defines the operating mode for the entire unit. There are two basic modes of
operation, master and follower. In master modes, the unit controls the load using rate or time
units. In follower mode, the unit controls the load in percentage of master rate.
Mode 1 – Master, Rate Mode
In Rate Mode, the drive displays in user-defined rate units such as RPM, Gallons per
Hour, or Feet per Second.
Mode 3 – Follower Mode
In Follower Mode, the drive displays in percentage units, where 1000 equals 100.0
percent of the master rate. For example, if the display indicates 985, 98.5, or 9.85, the
drive will attempt to run at exactly 98.5% of the master rate. Display settings are
always entered ignoring the decimal point's position.
Parameter 13 – Decimal Point (DP) Position
This selects the format of the display with respect to the decimal point’s position. This
parameter does not affect the value entry for other parameters. For example, if the user
desires to display 10.00 at 300RPM, then parameter 30 would be set to 1000, parameter 31
would be set to 300, and parameter 13 would be set to 2.
Mode 0: Fixed XXXX

Parameter 14 – Keypad Mode
This parameter selects the operating mode of the front-panel push buttons. In some
applications, increasing or decreasing the scroll rate provides the user more controllability
when entering settings. Parameters 14 and 15 affect only the Up and Down buttons when the
user interface is in Running Mode.
Mode 1: Linear, Constant Rate
In linear mode, pressing and holding the Up or Down buttons will cause the display to
continuously change value in the requested direction until either the Display Minimum
or Display Maximum is reached. The displayed value will scroll at a constant rate which
is specified using parameter 15.

Mode 2: Non-linear, Accelerating Rate
In non-linear mode, pressing and holding the Up or Down buttons will cause the display
to continuously change value in the requested direction until either the Display
Minimum or Display Maximum is reached. The displayed value will initially scroll at a
slow rate and increase in speed until the maximum scroll rate is achieved. The initial
scroll rate is specified using parameter 15.
Parameter 15 – Keypad Scroll Mode
This parameter sets the scroll speed for the front-panel push buttons. The function of this
parameter varies slightly depending on the Keypad Mode. See parameter 14 for more details.
Parameter 16 – S1 / S2 Input Edge & Prescaler Configuration
This parameter determines how the drive processes the S1 and S2 signal inputs. It specifies
which signal edge is used for measurements and the value of the internal frequency dividers
or prescalers. Modes with prescalers greater than 1 should only be used if the input pulse rate
on S1 or S2 exceeds the unit's maximum native pulse rate (see specifications for details);
otherwise, the control loop may become sluggish and unnecessarily inaccurate. Use the
following chart to configure this parameter. As an example, assume an application requires
input pulse rates on S1 of 120,000 pulses-per-minute and S2 of 35,000 pulses-per minute.
According to the electrical specifications, the unit can only accept 50,000 pulses per-minute
on each the S1 and S2 inputs. With this in mind, the S1 and S2 prescalers should be selected
as Falling / 4 and Rising / 1, respectively. In this case, parameter 16 would be set to 2.
Parameter 18 – Power-up Mode
This parameter defines the mode which determines the default Running Value when power is
initially applied to the drive.
Mode 1: Default to Zero
When in this mode, the unit will default to zero (display units).
Mode 2: Default to Power-Up Value
When in this mode, the unit will default to the Power-up Value, parameter 19.
Mode 3: Default to Previously Running Value
When in this mode, the unit will default to the previous running value before power was
removed. A previous running value must have been active for at least 3 seconds to
be recalled after power has been disconnected and reapplied.
Mode 11: Display Intensity
Set value between 0-31 to adjust display brightness (31=brightest).

Parameter 19 – Power-up Value
When Power-up Mode is set to 2, this parameter will designate the default display value at
power-up in display units.
Parameter 20 – Display Minimum
This parameter defines the lower end of the display range. This is the value which limits how
low the user is able to scroll the displayed value in Running Mode. In Rate and Time modes,
this value is set in display units. In Follower Mode, this is set in percentage of the master
rate. For example, in Follower Mode, 1250 represents 125.0 percent of the master rate. This
value can be changed but the feeder may not run consistently (choppy operation) if the
number of pulses per minute from the extruder are insufficient.
Parameter 21 – Display Maximum
This parameter defines the upper end of the display range. This is the value which limits how
high the user is able to scroll the displayed value in Running Mode. In Rate and Time modes,
this value is set in display units. In Follower Mode, this is set in percentage of the master
rate. For example, in Follower Mode, 150 represents 15.0 percent of the master rate.
Parameter 23 – Acceleration Setting
This parameter determines how fast the drive will accelerate toward the displayed target
setting. This parameter is set in display units of change per second such as RPM, GPM, or
feet per second. In Follower Mode, this parameter is set in RPM units.
Parameter 24 – Deceleration Setting
This parameter determines how fast the drive will decelerate toward the displayed target
setting. This parameter is set in display units of change per second such as RPM, GPM, or
feet per second. In Follower Mode, this parameter is set in RPM units.
Parameter 26 – Proportional (P) Gain
The Proportional Gain is the first of two parameters which define the responsiveness of the
control with respect to how fast it responds to changing loads. Because the drive controls are
pulse-accumulation drives, the P Gain responds differently than the same parameter in a
standard velocity-form PID control. The higher the P Gain, the more aggressively the unit
will drive the load.
Parameter 27 – Integral (I) Gain
The Integral Gain is the second of two parameters which define the responsiveness of the
control with respect to how fast it responds to changing loads. The higher the I Gain, the
more aggressively the unit will drive the load. When using high PPR pickups or encoders, it
will be necessary to decrease the I Gain to prevent unwanted oscillation and instabilities.
Parameter 30 – Signal Input 1 (S1) Display Reference
This is the number to be displayed when at the user-specified motor Reference RPM. In Rate
Mode, this value represents rate units such as feet, ounces, or revolutions. In Time Mode,
this value represents the reference time measured in seconds or minutes. If the desired
display is HH:MM, then all values should be entered in minutes. If MM:SS is desired, then
all values should be entered in seconds. In Follower Mode, this value is the percentage of the
master rate in 0.1% units. For example, 1000 equates to 100%.

Parameter 31 – Signal Input 1 (S1) Reference RPM
This is the reference RPM at which the Display Reference value should be displayed. In Rate
and Time Modes, this value represents the RPM of the encoder to which the Display
Reference corresponds. In Follower Modes, this value is not used.
Parameter 32 – Signal Input 1 (S1) Pulses per Revolution
This is the number of pulses per revolution for the signal input 1 (S1). The drive supports
pickups and encoders from 1 to 2048 pulses per revolution.
Parameter 33 – Signal Input 1 (S1) Deadband (Follower Mode Only)
When in Follower Mode, it is often desirable for the follower unit to continue to slowly
make-up the small pickup pulse differential between the master and follower's position. In
some applications, it is not necessary for the follower to continue to slowly seek the master's
exact pulse position when the master rate is at zero. In these cases, the Deadband parameter
can be set above zero to force the drive to stop driving the motor slowly and cause it to inhibit
until the master starts rotating again. At that point, the follower will automatically make-up
the pulse differential as it starts to rotate. The deadband is disabled by setting it to zero
seconds.
Parameter 35 – Signal Input 2 (S2) Input Configuration
This parameter determines the operating mode of signal input 2 (S2).
Mode 1: Disabled (Follower Mode)
The S2 input is inactive. This is the required setting for Follower Mode.
Mode 2: Emergency Stop When S2 High (Not Wired To Common)
When the S2 input is at an electrically high (+5V) state or allowed to float disconnected, the
drive will enter emergency-stop mode. While in this mode, the armature output will
immediately be turned off. Once the S2 input returns to an electrically low state or wired to
the unit's common, the output will become active.
Mode 3: Emergency Stop When S2 Low (Wired To Common)
When the S2 input is at an electrically low state or wired to the unit's common, the drive will
enter emergency-stop mode. While in this mode, the armature output will immediately be
turned off. Once the S2 input returns to an electrically high (+5V) state or allowed to float
disconnected, the output will become active.
Mode 4: Inhibit When S2 High (Not Wired To Common)
When the S2 input is at an electrically high (+5V) state or allowed to float disconnected, the
drive will enter inhibit mode. While inhibited, the armature output will decrease according to
the decel setting until zero output is reached. Once the S2 input returns to an electrically low
state or is wired to the unit's common, the output will start to accelerate toward the previous
running value.
Mode 5: Inhibit When S2 Low (Wired To Common)
When the S2 input is at an electrically low state or wired to the unit's common, the drive will
enter inhibit mode. While inhibited, the armature output will decrease according to the decel
setting until zero output is reached. Once the S2 input returns to an electrically high (+5V)
state or allowed to float disconnected, the output will start to accelerate toward the previous
running value.

Parameter 36 – Signal Input 2 (S2) Setpoint
When the S2 configuration, parameter 35, is set to one of the jog modes, this parameter
defines the jog setpoint in display units. If the drive operating mode is set to Follower Mode,
then this parameter is set in RPM units. This allows a follower control to be jogged when the
master is stopped.
Parameter 37 – Signal Input 2 (S2) Pulses per Revolution
This is the number of pulses per revolution for the signal input 2 (S2). The drive supports
pickups and encoders from 1 to 2048 pulses per revolution.
Parameter 95 – Factory Default Command
When set to a value of 5, the unit will be reset to factory default settings. This can also be
achieved by applying power to the unit with both the Enter and Down buttons depressed. The
programming jumper must be in the "On" position for this method to function.
Parameter 98 – Save to User Default Area Command
When set to a value of 5, the unit will store all adjustable parameters to the user default area.
The user default area is intended to be a location where an end user can store settings specific
to their application. Using this, an end user can easily refresh their custom settings in the
field if an someone accidentally reconfigures the unit unsuccessfully. Another common use
for this area is testing and initial setup. The user can store known-good settings here and
easily experiment without the fear of losing the optimal configuration.
Parameter 99 – Restore from User Default Area Command
When set to a value of 1, the unit will restore the all adjustable parameters from the user
default area. See parameter 98 for additional information.

Chapter 7: Troubleshooting
7-1 Introduction
The utmost in safety precautions should be observed at all times when working on or around
the machine and the electrical components. All normal troubleshooting must be accomplished
with the power off, line fuses removed, and with the machine tagged as out of service.
The use of good quality test equipment cannot be over-emphasized when troubleshooting is
indicated. Use a good ammeter that can measure at least twice the AC and DC current that
can be encountered for the machine. Be sure that the voltmeter has at least minimum
impedance of 5,000 OHMS-per-volt on AC and 20,000 OHMS-per-volt on DC scales.
Popular combination meters, VOM and VTVM can be selected to provide the necessary
functions.
Before making haphazard substitutions and repairs when defective electrical components are
malfunctioning, we recommend that you check the associated circuitry and assemblies for
other defective devices. It is common to replace the obviously damaged component without
actually locating the real cause of the trouble. Such hasty substitutions will only destroy the
new component. Refer to wiring diagrams and schematics.
Locating mechanical problems, should they occur, is relatively straightforward. When
necessary, refer to the parts catalog section.
