ICP DAS USA 3-axis encoder card, 2-axis stepping/servo user manual Output pulse mode configuration

I-8091 User Manual Version 1.0 06/2001

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

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.
