STR2 Hardware Manual

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

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”.
