Included in the LYNX shipping package is a CD with the IMS Terminal software. This is a programming/
communications interface created by IMS to simplify the use of the LYNX. There is a 32 bit version for
Windows 9x/NT4/2000 located on the CD. The IMS Terminal is also necessary to upgrade the software in
your LYNX Control Module. These updates will be posted to the IMS website at http://www.imshome.com/
as they are made available.
To install the IMS Terminal to your hard drive, insert the CD into your CD-ROM Drive. The CD should
autostart to the IMS Main Index Page. If the CD does not autostart, click “Start > Run” and type
“x:\IMS.exe” in the “Open” box and then click OK. NOTE: “x” is your CD ROM drive letter.

Te s t in g t h e LYN X S e t u p
Two basic instructions for communicating with a control module are SET and PRINT. The SET instruc-
tion is assumed and can be left off when communicating in ASCII mode. (You are in ASCII mode whenever
you are using a text based terminal.) It is used to set variables and flags that define control module opera-
tion. The LYNX Software automatically recognizes the SET instruction whenever the name of the variable or
flag is typed into the terminal. Here we will set the motor units variable (MUNIT) to 51200 by typing the
following at the prompt (>):
MUNIT = 51200
The PRINT instruction is used to report the values of variables and flags. Now, double-check the value of
MUNIT by typing the following at the prompt (>):
PRINT MUNIT
The return from your terminal should be 51200. Note that the case is not important for instructions,
variables, and flags. They may be typed in upper or lower case.
Use the SLEW instruction to move the motor at a constant velocity. Be sure that the velocity provided is a
reasonable value for your motor and drive and try to move the motor. For instance, at the prompt type:
SLEW 10
This will move the motor at a speed of 10 munits per second. If the motor does not move, verify that the
wiring is in accordance with Figure 1.1. If a non IMS driver is being used, you may need to consult the user
manual for that device.

Once you have been able to move the motor, the next step is to write a simple program to illustrate one of the
dynamic features of the LYNX: the ability to convert motor steps to a dimension of linear or rotary distance.
Let’s begin by discussing the relationship between the MUNIT variable and user units. Typically when we
perform a move we want to know the distance of that move in a familiar unit of measurement. That means
translating motor steps to the desired unit of measurement. The LYNX Control Module has the capability of
doing this for you. You have already set the motor units variable (MUNIT) to a value 51,200. With the
driver set to a resolution of 256 micro-steps per step and a 1.8° step motor that will be equal to 1 revolution
of the motor, or one USER UNIT. A user unit can be any unit of measure. At this point, by entering the
instruction MOVR 1, the motor will turn one complete revolution relative to its current position. Therefore,
1 User Unit = 1 Motor Revolution. For the exercise below we will use degrees for our user unit. As the LYNX
Product Manual indicates, the calculation required to select degrees as our user unit in this case is:
51200 Micro-steps per rev ÷ 360 degrees = 142.222 Micro-steps per degree
By setting the MUNIT variable to 51200/360 the LYNX Control Module will perform the calculation to
convert the user unit to degrees. Now, when issued, a relative motion instruction “MOVR 90” the motor will
turn 90 degrees.
Now, enter a sample program that will convert motor steps to degrees, execute a 90° move, and report that
move every 100 milliseconds while the motor is moving. Type the following bold commands:
‘Enter Program Mode, start program at Location 2000.
PGM 2000
‘Label the program TSTPGM.
LBL TSTPGM
‘ Set the user units to degrees.
MUNIT = 51200/360
‘ Set the max. velocity to 25 degrees per second.
VM = 25
‘ Execute a relative move of 90 degrees.
MOVR 90
‘ Report the position every 100 ms while moving.
LBL PRINTPOS
DELAY 100
PRINT “Axis position is”, POS, “Degrees.”
BR PRINTPOS, MVG
‘End the program.
END
PGM
Now Type TSTPGM to run program.
This sample program will be stored starting at location 2000. It sets the conversion factor for the user units,
sets the maximum velocity and then starts a motion. While the motion is occurring, the position is reported
every 100 milliseconds.
At this point you may desire to restore the settings to their factory default as you may not wish to use
degrees as your user unit. To do this, you will use the CP, DVF, and IP instructions.
CP - Clear Program.
To clear the program, type CP 1, 1. This will completely clear program memory space. Should
you desire to only remove one program, the instruction “CP [Program Label]” i.e., “CP
TSTPGM” would clear only that program. In this exercise only one program was entered, “CP
TSTPGM” will clear it.
DVF - Delete User Defined Variables and Flags.
By entering DVF, all of the user defined variables will be removed. Although no Flags were set
in this exercise, this command would clear them were they used.
IP - Initialize Parameters
This instruction will restore all of the parameters to their factory default state.
After entering these instructions a SAVE instruction should be entered.

This section covers the two basic power configurations for your LYNX System.

Basic rules of wiring and shielding.

LYNX Control Module as Stand-alone or with Optional I/O Module.
W ir in g a n d S h ie ld in g
Noise is always present in a system that involves high power and small signal circuitry. Regardless of the
power configuration that you use in your system, there are some wiring and shielding rules that you should
follow to keep your noise-to-signal ratio as small as possible.
R u le s o f W ir in g
!
Power Supply and Motor wiring should be shielded twisted pairs run separately from signal
carrying wires.
!
!
A minimum of 1 twist per inch is recommended.
Motors wiring should be shielded twisted pairs using 20-gauge wire, or 18 gauge or better for
distance greater than 5 feet.
!
!
Power ground return should be as short as possible to established ground.
Power Supply wiring should be shielded twisted pairs. Use 18 Gauge wire if load is less than 4
amps, or 16 gauge for more than 4 amps.
!
Do not “Daisy-Chain” power wiring to system components.
R u le s o f S h ie ld in g
!
!
The shield must be tied to zero-signal reference potential. In order for shielding to be effective
it is necessary for the signal to be earthed or grounded.
Do not assume that earth ground is true earth ground. Depending on the distance to the main
power cabinet it may be necessary to sink a ground rod at a critical location.
!
!
The shield must be connected so that shield currents drain to signal-earth connections.
The number of separate shields required in a system is equal to the number of independent
signals being processed plus one for each power entrance.
!
!
The shield should be tied to a single point to prevent ground loops.
A second shield can be used over the primary shield, however the second shield is tied to
ground at both ends.
WARNING! When using an unregulated supply, ensure that the
output voltage does not exceed the maximum driver input voltage
due to variations in line voltage! It is recommended that an input line
!
filter be used on power supply to limit voltage spikes to the system!

In this example, power is connected to the LYNX Control Module via connector P1. All optional plug-on
modules are then powered from the LYNX Control Module. In this configuration, pins 5 and 6 on connector
P2 of the Control Module become +5VDC (150mA, internally limited) regulated outputs. If an encoder is to
be used in the system, it may be powered via these pins. Below is a table of recommended power supply

The LYNX Control Module features two communication interfaces: RS-232 and RS-485. For both channels,
the BAUD rate is software configurated, using the BAUD variable, to 4800, 9600, 19200 or 38400 bits/sec.
The factory default is set to 19200 bits/sec. Default data settings are 8 data bits, 1 stop bit and no parity.
A host computer can be connected to either interface to provide commands to the control module or to
multiple control modules in a system. Since most personal computers are equipped with an RS-232 serial
port, it is most common to use the RS-232 interface for communications from the host computer to the
control module. You will typically want to use this interface option if your Host PC will be within 50 feet of
your system. Should your system design place the LYNX Control Module at a distance greater than 50 feet,
it will be necessary for you to use the RS-485 interface option. You can accomplish this by using either an
RS-232 to RS-485 converter, such as the converter sold by IMS (Part # CV-3222), or installing an RS-485
board in an open slot in your host PC.

In systems with a single control module, also referred to as Single Mode, the LYNX Control Module is
connected directly to a free serial port of the Host PC. Wiring and connection should be performed in accor-
dance with the following table and diagram. In this mode the PARTY switch will be in the OFF position, and
the PARTY Flag will be set to 0 in software. This is the factory default setting. Please be aware that you
cannot communicate with the LYNX Control Module in single mode unless those conditions exist.
WARNING! Failure to connect communications ground as
shown may result in damage to the Control Module and/or
Host!
!
NOTE: If using the RS-232 Interface Option, the Host PC MUST
be less than 50 feet from the Control Module. If your system
will be greater than 50 feet from the Host PC you must use the
RS-485/RS485 Interface.

Figure 5.1: Connecting the RS-232 Interface, Single Control Module System
M u lt ip le C o n t r o l M o d u le S y s t e m
When connecting multiple control modules in a system using the RS-232 interface, it is necessary to
establish one control module as the HOST. This control module will be connected to the Host PC exactly as
the system using a single control module. The system HOST is established by one of two methods, by
manually selecting the Host switch (configuration switch #2, labeled HI) to the ON position, or by setting
the HOST Flag to True (1) in software. The remaining control modules in the system must then be connected
to the HOST control module using the RS-485 interface and will have their Host switch set to OFF (HOST
Flag = 0).
In this interface configuration, Host PC communications will be received by the Host Control Module via
RS-232 and forwarded to all of the other control modules in the system via the RS-485 channel. Responses
from the individual control modules in the system will be routed back to the Host Control Module via the
RS-485 channel, then internally converted to RS-232 before being forwarded back to the Host PC.
In systems with multiple controllers it is necessary to communicate with the control modules using PARTY
Mode of operation. The LYNX Control Modules in the system are configured for this mode of operation by
setting the Party Switch (configuration switch #3, labeled PT) to the ON position, or setting the PARTY Flag
to True (1), in software. It is necessary for all of the controllers in a system to have this configuration
selected. When operating in PARTY Mode each control module in the system will need a unique address, or

name, to identify it in the system. This can be done using configuration switches A0-A2, or by using the
software command SET DN. For example, to set the name of a controller to "A" you would use the following
command: SET DN = "A". The factory default name is "!". To set the address of the controller using the
configuration switches use the following table:

Table 5.2: Party Mode Address Configuration Switch Settings
In setting up your system for PARTY operation the most practical approach would be to observe the
following steps:
1.
2.
Connect the Host Control Module to the Host PC configured for single mode operation.
Establish communications with the HOST Control Module. (For help in doing this see Software
Reference: Using the LYNX Terminal.) Using the Command: SET DN or the configuration
switches, give the controller a unique name. If using the software command this can be any
upper or lower case ASCII character or number 0-9. Save the name using the command SAVE.
3.
4.
Set the appropriate HOST and PARTY configuration in accordance with the table and diagram
below. Remove power.
Connect the next control module in the system in accordance with the following table and
diagram, setting the PARTY switch in the ON position. If you desire you can set the PARTY
Flag to “1” in software later and turn the switch off.
5.
6.
Establish communications with this module using the factory default name “!”. This name
cannot be reused. Rename and save the new name. Remove power.
Repeat the last two steps for each additional control module in the system.
WARNING! Failure to connect communications ground as
shown may result in damage to the Control Module and/or Host!
!
NOTE: If using the RS-232 Interface Option, the Host PC MUST
be less than 50 feet from the Control Module. If your system
will be greater than 50 feet from the Host PC you must use the
RS-485/RS485 Interface.

Data Cable lengths greater than 15 feet (4.5 meters) are susceptible to signal reflection and/or noise. IMS recommends
120Ω termination resistors at both ends of the Data Cables. An example of resistor placement is shown in Figure 5.4.
For systems with Data Cables 15 feet (4.5 meters) or less, the termination resistors are generally not required.

LYN X C o n t r o l M o d u le M o d e s o f O p e r a t io n
YNXSystem
There are three modes of operation for the LYNX control module. These are Immediate Mode, Program
Mode, and EXEC Mode.
Im m e d ia t e M o d e
In this mode, the control module responds to instructions from the user that may be a result of the user
typing instructions directly into a host terminal, or of a user program running on the host which commu-
nicates with the control module.
P r o g r a m M o d e
The second mode of operation of the control module is Program Mode. All user programs are written in this
mode. Unlike the other modes of operation, no commands or instructions can be issued to the control
module in Immediate Mode. This mode is exclusively for writing programs for the controller. The
command to enter Program Mode is PGM <address>. When starting Program Mode, you must specify at
what address to enter the program instructions in the program space. Simply type PGM again when you
have finished entering your program commands to go back to Immediate Mode.
E XE C M o d e
In EXEC Mode a program is executed either in response to the EXEC instruction from the user in Immediate
Mode, or in response to a specified input. While the control module is running a program, the user may still
communicate with it in Immediate Mode. As part of a user program, the control module may start a second
task using the RUN instruction. Thus, there can be two tasks running on the control module at the same
time, a foreground task (started by the EXEC instruction in Immediate Mode) and a background task (started
by the RUN instruction in Program Mode).
LYN X C o n t r o l M o d u le C o m m u n ic a t io n M o d e s
When the control module is operating in Immediate Mode, there are two methods of communicating. The
first is ASCII where the instructions are communicated to the control module in the form of ASCII mnemon-
ics and data is also given in ASCII format. The second is binary where the instruction is in the form of an
OpCode and numeric data is given in IEEE floating point hex format. In binary mode, there is also the option
of including a checksum to ensure that information is received properly at the control module. The BIO flag
controls the method of communication. When it is True (1) the binary method should be used, and when it is
False (0) the ASCII method should be used.
A S C II
ASCII is the most common mode of communicating with the LYNX System. It allows the use of readily
available terminal programs such as HyperTerminal, ProComm, and the new IMS Terminal.
When using the ASCII method of communications, the control module tests for four special characters each
time a character is received. These characters are given in the table below along with an explanation of what
occurs when the character is received.
The command format in ASCII mode when the control module is in Single Mode (PARTY = FALSE) is:
<Mnemonic><white space><ASCII data for 1st parameter>, <ASCII data for 2nd parameter>, … , <ASCII data
for nth parameter><CR/LF>
The mnemonics for Control Module instructions, variables, flags and keywords are given in Part III
Software Reference of this manual. White space is at least one space or tab character. CR/LF represent the

Table 5.7: ASCII Mode Special Command Characters
carriage return line feed characters that are transmitted in response to the Enter key on the keyboard
provided the ASCII setup specifies “Send line feeds with line ends”. Note that there need not be a space
between the data for the last parameter and the CR/LF. Also note that if there is only one parameter, the CR/
LF would immediately follow the data for that parameter.
The command format in ASCII mode when the control module is in Party Mode (PARTY = TRUE) would be
identical to that in Single Mode with the exception that the entire command would be preceded by the
control module’s address character (stored in DN) and terminated by a CTRL-J rather than ENTER:
<Address character><Mnemonic><white space><ASCII data for 1st parameter>, <ASCII data for 2nd param-
eter>, … , <ASCII data for nth parameter><CTRL-J>
B i n a r y
Binary mode communications is faster than ASCII and would most likely be used in a system design where
the communication speed is critical to system operation. This mode cannot be used with standard terminal
software.
The command format in binary mode when the control module is in Single Mode (PARTY = FALSE) is:
<20H><character count><opcode><Field type for 1st
parameter><IEEE hex data for 1st parameter><0EH><Field type

Note that <20H> is 20 hex, the character count is the number
of characters to follow the character count not including the
checksum if one is being used. The OpCodes for control
module instructions, variables, flags and keywords are given
in Sections 15 and 16 of this document. The Field type byte
will be one of the following based on the type of data that is
expected for the specific parameter:
1 byte unsigned
2 byte signed
2 byte unsigned
4 byte signed
4 byte unsigned

<0EH> is 0E hex, which is a separator character in this mode.
Finally, the optional checksum will be included if CSE is TRUE
and excluded if it is FALSE. If included, the checksum is the
low eight bits of the complemented sixteen-bit sum of the
address field (20H here), character count, OpCode, all data
fields and separators (0E hex).

Th e Is o la t e d D ig it a l I/ O
The LYNX CM100 Control Module has a standard set of twelve +5 to +24VDC I/O lines and the LYNX
CM200 Combination Control Module has a standard set of six +5 to +24VDC I/O lines. These I/O lines may
be programmed individually as either general purpose or dedicated inputs or outputs, or collectively as a
group. The Isolated Digital I/O may be expanded to a maximum of twenty-four (24) lines on the CM100 and a
maximum of eighteen (18) lines on the CM200.
The I/O groups and lines are numbered in the following fashion:
Group 20 = Lines 21 - 26 (Standard CM100 and CM200)
Group 30 = Lines 31 - 36 (Standard CM100 only)
Group 40 = Lines 41 - 46 (Optional CM100 and CM200)
Group 50 = Lines 51 - 56 (Optional CM100 and CM200)
The isolated digital I/O may be defined as either active HIGH or active LOW. When the I/O is configured as
active HIGH, the level is +5 to +24 VDC and the state will be read as a “1”. If the level is 0 VDC then the
state will be read as “0”. Inversely if configured as active LOW, then the state of the I/O will be read as a “1”
when the level is LOW, and a “0” when the level is HIGH. The active HIGH/LOW state is configured by the
third parameter of the IOS variable, which is explained further on. The goal of this I/O configuration scheme
is to maximize compatibility between the LYNX and standard sensors and switches. The LYNX I/O scheme is
a powerful tool for machine and process control. Because of this power, a level of complexity in setup and
use is found that doesn’t exist in controllers with a less capable I/O set.
U s e s o f t h e Is o la t e d D ig it a l I/ O
The isolated I/O may be utilized to receive input from external devices such as sensors, switches or PLC
outputs. When configured as outputs, devices such as relays, solenoids, LED’s and PLC inputs may be
controlled from the LYNX. Depending on the device connected, the input or output may be pulled-up to
either the internal +5VDC supply or an external +5 to +24VDC supply, or the I/O lines may be pulled-down to
ground. These features, combined with the programmability and robust construction of the LYNX I/O open
an endless vista of possible uses for the I/O in your application.

Each I/O line may be individually programmed to any one of 8 dedicated input functions, 7 dedicated output

The active state of the line or group may also be set. All of these possible functions are accomplished with

T h e IO S Va r ia b le
The IOS variable has three parameters when used to configure the isolated digital I/O. These are:
YNXSystem
1]
I/O Line Type: Specifies the the type of I/O that the line or group will be configured
as, i.e. general purpose or dedicated function.
2]
3]
I/O Line Function: Either an input or an output.
Active State: Specifies whether or not the line will be active HIGH or active LOW.
The default configuration of the standard I/O set is: 0,0,1. This means that by default each line in group 20 is
configured to be a General Purpose (0), Input (0), which is active when HIGH (1). The following figure and
exercises illustrate possible configurations of the IOS.

Figure 6.2 below illustrates the Input Equivalent Circuit of the Isolated I/O being used with a switch. To
illustrate the usage of an input you will go through the steps to configure this switch to start a simple
program at Line 1000 to index a motor 200 user units. First you must configure the I/O Line 21 as a “GO”
input:
4.5V Internal
Pullup
Pull-up Switch = CLOSED
IOS 21 = 9, 0, 0
To break this command down:
PUSH BUTTON
SWITCH
IOS 21 - Identifies the I/O Line we are
setting as 21.
9 - Configures the I/O Type to “GO”.
0 - Configures I/O as Input.
0 - Configures I/O as Active LOW.
I/O LINE
When the Input Type “GO” is selected
it will always look to execute a
I/O GND
program located at line 1 of program
memory. Therefore, to run a program at
line 1000 you must do the following:

able to sink 350mA continuous for each output, or a total of 1.5A for the entire I/O Group. See Section 9:
The Isolated Digital I/O Module for detailed specifications. In the usage example we will use an LED on I/O

After configuring the I/O by means of the IOS variable, we need to be able to do two things with the I/O.
1]
2]
Write to an output, or group of outputs, thus setting or changing its (their) state.
Read the states of either inputs or outputs. We can use this information to either display those
states to our terminal, or to set up conditions for branches and subroutine calls within a program.
We can also use this command to write or read the state of an entire I/O group.
R e a d / W r it e a S in g le I/ O Lin e
To read the state of a single input or output, the following would be typed into the terminal:
PRINT IO 21
The response from this would be 1 or 0, depending on the state of the line.
The state of an input or output in a program can be used to direct events within a LYNX program by either
calling up a subroutine using the “CALL” instruction, or conditionally branching to another program
address using the “BR” instruction. This would be done in the following fashion.
CALL MYSUB, IO 22=1
This would call up a subroutine labled “MYSUB” when I/O line 21 is active.
BR 200, IO 22=0
This would branch to address 200 when I/O line 22 is inactive.
Writing to an output is accomplished by entering the following into a terminal or program:
IO 21=1
IO 21=0
This would change the state of I/O line 21.

When using the IO variable to read the state of a group of
inputs/outputs, or write to a group of outputs you would first
want to configure the entire I/O group to be general purpose
inputs or outputs using the IOS variable. In this case the
response or input won’t be a logic state of 1 or 0, but rather the
decimal equivalent (0 to 63) of the 6 bit binary number repre-
sented by the entire group.

Quadrature
The LYNX has four clock pairs that are used by the high speed I/O. One of these, clock
pair 11 and 12, is fixed as an output and is used internally to provide step clock and
direction pulses to Step Clock and Direction outputs located on Connector P1 of the
LYNX Controller. The step clock output increments CTR1 (Counter 1). CTR1 may be
read from or written to by software instructions in either program or immediate mode.
The following table explains the clocks, as well as their default I/O line pair placement.

The high speed differential I/O is configured by means of the IOS variable, and is used in the the same
fashion in which the isolated I/O is configured. The main difference lies in that there are three additional
parameters which need to be set in configuring the triggering, clock type, and ratio mode setting.
It is important to note that the high speed differential I/O lines may be used for the same input or output functions
as the isolated digital I/O where the higher speed capabilities of the differential I/O is required. However, for
purposes of this example we will only illustrate the clock functions associated with the high speed differential I/O.
Figure 6.5 following illustrates the IOS variable settings for the high speed differential I/O.

Clocks 2, 3 and 4 can be configured as high speed inputs, or as a general purpose input in the same fashion
as the Isolated I/O. In configuring the Differential I/O line as a general purpose input you would typically
use the “+” line of the line pair. You cannot use both lines as separate I/O lines. The figure below shows the

In the Equivalent Circuit in Figure 6.7 an Output is being used as Step or Direction on a driver.
For the configuration example, use I/O line 13 for the output. Since by default the line is a quadrature input
we must configure it to be a Step/Direction Output by setting the IOS Variable to the following:
IOS 13 = 3, 1, 0, 1, 2, 0
This breaks down as:
IOS 13 - Identifies the line being configured as 13.
3 - Sets the I/O Type to Clock 2A (default).
1 - Sets it as an output.
0 - Sets Logic at Low True.
1 - Edge Triggered.
2 - Sets the Clock Type to Step/Direction.
0 - No Ratio.

The differential I/O module can be set up to receive encoder feedback using either a differential or a single
ended output encoder. A differential output encoder would typically be connected to differential input pairs
13 and 14 (P1, pins 1 – 4) as the default setting for I/O 13 and 14 is set up to accept a quadrature encoder
input. Channel A of the encoder would be connected to input pair 13 (P1, pins 1 & 2) and channel B would
be connected to input pair 14 (P1, pins 3 & 4). A single ended output encoder would be connected to the
positive inputs of the input pair. Whether you use a differential encoder or single ended encoder the same
software commands and settings will be used.
In setting up your system to run with an encoder you will be using the following variables, flags, and
instructions. The variables used with an encoder will be MUNIT, EUNIT, CTR2, and POS. The Encoder
Enable Flag EE, and the instruction MOVR will be used. The block diagram to the left illustrates a LYNX
system with the encoder and drive connections that will be used in this example.
The sequence of commands (in bold) used to make this setup function would be as follows:
‘Set the MUNIT Variable to 51,200 steps/rev
MUNIT = 51200
‘Set encoder enable to TRUE (1), default value = FALSE (0)
EE = 1
‘Set the EUNIT (Encoder Units) variable to 800 (200 [Encoder Resolution] X 4 [Quadrature Input])
This means that 1 unit of motion, or 1 POS, is equal to 800 encoder counts. In this instance it will be
1 rotation of the motor.
EUNIT = 800
‘Save the above flag and variable settings
SAVE
Now you may begin to use the motion command MOVR, as well as PRINT POS and PRINT CTR2 to see the
number of encoder counts fed back to the system.
‘Set the motor position to 0
POS = 0
‘Move the motor 2 units (2 X EUNIT) relative to current position.
MOVR 2
‘Print the value of CTR2. This value will indicate the number of encoder counts that the motor has
moved. Your terminal should echo back the number “1600”.

By printing the variable CTR2 (CTR2 = EUNIT X POS) we can view the distance the motor has traveled in
raw encoder counts, or by printing POS you can see the distance of travel represented by number of units
relative to 0.

Tr a n s la t in g t h e E U N IT Va r ia b le t o a D im e n s io n o f D is t a n c e
The EUNIT, or Encoder Unit variable, is the scaling factor used to translate Encoder steps to a dimension of
distance, or user units. At this point you should already be familiar with the MUNIT variable. The main
difference between the two is as follows: By using MUNIT scaling factor you monitor the position of an axis
based upon the value of CTR1, the register that contains the actual count of clock pulses sent to the drive.
The number of pulses is then scaled to user units by setting the MUNIT Variable to the appropriate scaling
factor for the type of units being used, be they inches, millimeters, degrees, etc. Then the POS variable
tracks position in the user units specified. Example:
User Unit (POS) = CTR1 ÷ MUNIT where EE (Encoder Enable) Flag = FALSE (0)
By setting the state of EE, the master encoder function enable flag, to a true state you will monitor the
position of an axis based upon the actual position of the motor shaft as it is fed back to the Control Module

by a motor mounted encoder. The actual count of encoder pulses received by the Control Module is
maintained by the register CTR2, (if the encoder is connected to I/O line pair 13 &14) with the EUNIT
variable scaling it to user units. Example:
User Unit (POS) = CTR2 ÷ EUNIT where EE (Encoder Enable) Flag = TRUE(1)
When using the EUNIT scaling factor it is important to understand that you MUST set the EUNIT variable
AND the MUNIT variable to the same scaling factor for accurate position monitoring. In the example below
you will use a hypothetical system designed from the following components:
An IMS IB462H Half/Full Step driver configured for Half Step Operation.
A 1.8° Stepping Motor mounted to a 20cm linear slide.
A 200 Line Encoder.
You will want to use millimeters for our user unit. The IB462H in half step mode will need 400 clock pulses to
turn the motor one revolution. The pitch on the leadscrew is such that one millimeter of linear motion will
require 25 clock pulses. 400 steps/rev ÷ 25 steps/mm = 16 mm/rev. Therefore, you would set the MUNIT
variable as follows:
MUNIT = 400/16
Now, when you give a MOVR 20 instruction, the axis will index 20 millimeters. Now to set the EUNIT
Variable. We have a 200 line encoder connected to a quadrature clock input. This will mean that 1 revolution
will equal 800 Encoder Pulses, you will have to use the same scaling factor as we did for MUNIT as there will
still be 16mm per revolution:
EUNIT = 800/16
Both values must be set, and both must be set to the same scaling factor. With the EE = 1 a MOVR 20
command will still index the axis 20 millimeters, but position will be maintained by CTR2.
H a lf A x is O p e r a t io n ( F o llo w e r )
In half axis mode the master clock is taken from a clock input 2, 3 or 4 (line pairs 13-14, 15-16 or 17-18) which
have been set for input, clock type and ratio enabled. This is the factor at which the count rate out to the
primary drive will follow the external clock in half axis mode. This clock input would typically be connected
to differential input pairs 15 and 16 (P1, pins 5 – 8). This could be set up as any of the available clock types.
If half axis mode is enabled (HAE), the primary axis of the control will follow the clock input with the ratio
specified by the HAS variable.
In order to use the HAS (Half axis mode scaling) variable the HAE flag must be set to true (1). For example,
to set the half axis scale factor to .5, where the drive will follow the external Clock input with a ratio of 1
count to the drive for every two counts from the external clock, you would use the command: SET HAS = .5
(or HAS = .5). Figure 6.9 illustrates the connections for using this mode of operation using a clock input
from an encoder.
The sequence of commands used to make this setup function would be as follows:
‘Set IOS 15 to ratio mode
IOS 15 = 5,0,1,0,1,1
‘Set IOS 16 to ratio mode
IOS 16 = 6,0,1,0,1,1
‘Half axis enable set to true
HAE = 1
‘Half axis scaling to .5 (1 output clock pulse to every 2 input clock pulses)
HAS = .5

A secondary drive can be connected to a pair of differential outputs. The secondary driver will operate off
of the differential output pair 15 and 16 (I/O pair 13 and 14 can also operate in this mode). Setting the
ratio mode to TRUE (1) for the differential output clock (IOS) specifies a secondary drive function. Then
when ratio mode is enabled (RATIOE); the secondary axis will follow the primary axis with the ratio
specified by the RATIO variable.
