Pulse/Dir/En Inputs - Arcus ACE-102 Manual

3.3. Pulse/Dir/En Inputs

ACE-102 supports both one-clock (Pulse/Dir) or two-clock (CW/CCW) inputs.
One-clock uses Pulse signal as the amount of movement and Dir signal as the
direction of the movement.
Two-clock uses CW as clockwise movement and CCW as counter clockwise
movement.
Depending on the direction polarity setting, actual direction of the stepper motor
rotation can be configured for the application.
Maximum pulse rate support is 300K pulses/second.
Pulse/Dir (CW/CCW)/Ena inputs are opto-isolated differential inputs with 220
Ohm resistor. 5V is recommended. If voltage across is greater than 5V, make
sure to add current limiting resistor to limit the current across the diode.
