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.

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
