There are four faults that will reduce amplifier current to zero.
LED
INDICATION
CONTINUOUS
If a load condition exists that causes the amplifier to
produce more than its continuous rating, this fault
occurs.
STATOR SHORTS/
POWER DEVICE
If stator shorts or most major wiring errors of the stator
occur, this fault occurs. This output also comes on if the
power device becomes too hot.
FEEDBACK WIRING
For most resolver wiring errors, defective resolvers or
tracking rate errors caused by the resolver, this fault
occurs.
MOTOR THERMAL
If an excess thermal condition exists in the motor, this
fault occurs.
POWER(GREEN)
If logic +5 Vdc is on then this LED is on.
