32 bits encoder counts command sets  
(6) void i8090_ENCODER32_ISR(unsigned char cardNo)

cardNo: 0~19, select which card.  
axis : select which axis.  
1 : X-axis  
2 : Y-axis  
3 : Z-axis  
The above three commands provided a software method to get 32 bits  
encoder counts.  
The i8090_ENCODER32_ISR(unsigned char cardNo) command  
calculates the difference pulse between present and last time, and then  
add this difference into a ”long type” variable. According to this idea, so,  
the i8090_ENCODER32_ISR() command should be executed  
periodically in 2~10ms by timer interrupt or manually call it.  
The i8090_RESET_ENCODER32((unsigned char cardNo,  
unsigned char axis) command can reset the “long type” variable to  
zero.  
The long i8090_GET_ENCODER32(unsigned char cardNo,  
unsigned char axis) command can return the value of the “long type”  
variable.

1.2 DDA Technology  
The DDA chip is the heart of I-8091 card, it will generate equal-space  
pulse train corresponding to specific pulse number during a DDA period.  
This mechanism is very useful to execute pulse generation and  
interpolation function. The DDA period can be determined by DDA cycle.  
Table(1) shows the relation among DDA cycle, DDA period and output  
pulse rate. When DDA cycle set to 1, the DDA period is equal to  
(1+1)x1.024ms = 2.048ms. The output pulse number can be set to 0~2047,  
therefore the maximum output pulse rate will be 1Mpps. The minimum  
output pulse rate is 3.83pps when set DDA cycle=254 (DDA period =  
(254+1)x1.024ms = 261.12ms).

2. The required speed resolution.  
The maximum output pulse number is Np(0~2047), therefore  
the speed resolution is Vmax(max. speed)/Np. The DDA cycle  
can be obtained by following equation.

as the speed resolution is acceptable.  
Example: Stepping Motor  
The specification of stepping motor is 500 pulse/rev, max. speed 500  
rpm, speed resolution 2 rpm.  
The required max. pulse rate  
PRmax = 500 rpm*500/60 = 4166.67 pps

2.4.2 Output pulse mode configuration  
I-8091 card provide two kind output method.  
(a) CW/CCW mode  
(b) Pulse/Direction mode  
The command i8091_SET_MODE(cardNo, modeX, modeY) provide  
parameters CW_CCW (0) and PULSE_DIR (1) to define output pulse  
mode.  
CW  
Mode = 0 (CW_CCW)  
CCW  
Pulse  
Mode = 1 (PULSE_DIR)  
Direction  
Fig.(7) Output pulse mode  
2.4.3 Direction configuration  
Sometimes, the output direction of X-axis, Y-axis is not in the  
desired direction due to the motor’s connection or gear train. It is  
recommended to unify the output direction as shown in Figure(5)(6). The  
CW/FW direction is defined as toward outside from motor and the  
CCW/BW direction is defined as toward inside to motor. The  
i8091_SET_DEFDIR(cardNo, defdirX, defdirY) command provides  
parameters NORMAL_DIR (0) and REVERSE_DIR (1) to define the  
rotating direction of motor.  
2.4.4 Turn Servo ON/OFF (Hold ON/OFF)  
To turn servo motor into servo ON(OFF) state, or turn stepping motor  
into hold ON(OFF) state, the command i8091_SET_SERVO_ON(cardNo,  
sonX, sonY) provide parameters ON (1) and OFF (0) to turn ON or OFF.  
2.4.5 Automatic protection  
The I-8091 card has a automatic protected system.  
(a) If X-aixs command is executing and moving toward CW/FW direction,  
2-12  
ICPDAS  
I-8091 User Manual  
Version 1.0 06/2001  
X-axis will immediately stop when LS14 is touched. To release this  
protection as long as X-axis move toward CCW/BW direction.  
(b) If X-aixs command is executing and moving toward CCW/BW  
direction, X-axis will immediately stop when LS11 is touched. To  
release this protection as long as X-axis move toward CW/FW  
direction.  
(c) If Y-aixs command is executing and moving toward CW/FW direction,  
Y-axis will immediately stop when LS24 is touched. To release this  
protection as long as Y-axis move toward CCW/BW direction.  
(d) If Y-aixs command is executing and moving toward CCW/BW  
direction, Y-axis will immediately stop when LS21 is touched. To  
release this protection, as long as Y-axis move toward CW/FW  
direction.  
(e) If the signal of the emergency limit switch /EMG was found in CPU  
firmware, all motion will be terminated and stop.  
2.4.6 Set limit switch as normal close condition  
The limit switches /EMG, /LS11, /LS14, /LS21, /LS24, /ORG1, /ORG2 is  
initially normal open condition, that is, these signal is active when  
connect it to ground. In industrial application, it might be recommended  
normal close condition, that is, these signal is active when open from  
ground.  
The i8091_SET_NC(cardNo, sw) command can be set sw=0 (default), for  
normal open condition. When set sw=1, for normal close condition.
