MM-PCM Series
Section 7. Diagnostic LEDs
MM-PCM series drives are equipped with four diagnostic LEDs:
• Current Limit (C/LIM): Red LED lights whenever the drive reaches
current limit.
• Inhibit (INH): Red LED lights whenever the inhibit circuit is active.
• Power (PWR): Green LED lights whenever AC line voltage is applied
to the drive.
• Run (RUN): Green LED lights whenever the drive is applying a signal
to the motor.
