Connecting Input Signals
The STR drives have three inputs:
• STEP: a high speed digital input for step pulse commands, 5-24 volt logic
• DIR: a high speed digital input for the direction signal, 5-24 volt logic
• EN: a 5-24V input for commanding the removal of power from the motor, EN input must be
open 50 milliseconds before pulses are received.
Note: STEP and DIR inputs can be converted to STEP CW and STEP CCW by moving the inter-
nal jumper. See “Step 6: Step Pulse Type”.
