The drive regulator has passed its internal power-up diagnostic tests. After
power-up this LED will turn off if the internal “watchdog timer” fault occurs.

P.M. FLT

Shorted SCR, Field Current Feedback too low or too high.

Loss of AC Line Synchronization, AC Line Missing, Instantaneous Over-Current
(IOC), Over-speed, User program has initiated the illumination of the LED.

COMM OK

Drive Comm is active and synchronized.

FDBK OK

The SD3000 Plus is receiving feedback from the resolver and no resolver feedback
faults have been detected. If the LED is off, one of the following faults may have
occurred:

• Feedback Loss Fault - armature voltage has exceeded 40% of the rated value

and speed feedback has been less than 5% of motor base speed

• Broken Wire Fault - a resolver sine or cosine signal is missing

fault circuit breaker.

AUX IN 3

Auxiliary Input 3 is energized. This input often indicates the status of the Power
Module’s airflow switch.

AUX IN 4

Auxiliary Input 4 is energized. This input often indicates the status of the motor
thermal switch.

AUX IN 5
