Pulse/direction signals (CLK/#CLK/DIR/#DIR)
Through these signals, the motor controller can be controlled by a stepper motor control card.
Signal
Description
CLK/#CLK
Pulse signals for control of the rotations/speed.
DIR/#DIR
Direction signals for control of the direction of rotation.
–
DIR = high: Positive direction of rotation
–
DIR = low: Negative direction of rotation
