INDICATION
This is an output that comes ON at the resolver zero
position and can be used in conjunction with alignment
procedures. The zero position is about .5 degrees.
green as a function of load. The intensity increases with
load. Red indicates positive torque and green indicates
negative torque.
INDICATION
If an excess current or speed variation is sensed, this
fault occurs.
If shorts in the stator wiring occur, this comes ON.
heat sink and shunt load. If an excess temperature is
sensed, this fault occurs.
For most resolver wiring errors, defective resolvers or
tracking rate errors caused by the resolver, this fault
occurs.
If an excess thermal condition exists in the motor, this
fault occurs.
If excess DC voltage or a failure of the shunt circuit
occurs, this fault occurs.
During the first second of power up or if the reset input
is active, this LED will be ON.
This LED is ON if the motor is running slow or has
stopped.
INDICATION
If logic +5 Vdc is ON then this LED is ON.
