Connecting Input Signals
The STM23R has 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 switch #8 to the ON position. See Page 21.
