Fault messages generated by the drive

FAULT CAUSE
ACS800 TEMP Drive IGBT temperature is excessive. Fault trip
limit is 100%.
(4210)
3.05 FW 1 bit 3
ACS TEMP xx y Excessive internal temperature in inverter unit
of several parallel connected inverter modules.
(4210)
xx (1...12) refers to inverter module number
3.05 FW 1 bit 3 and
and y refers to phase (U, V, W).

WHAT TO DO
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against unit power.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against unit power.
Check for proper analogue control signal
levels.
Check control wiring.
Check Fault Function parameters.
Consult the documentation or author of the
Adaptive Program.
Retry.
Check connections.
Check that parameters are compatible with
drive.
Let chopper cool down.
Check parameter settings of resistor overload
protection function (see parameter group
BRAKE CHOPPER).
Check that braking cycle meets allowed limits.
Check that drive supply AC voltage is not
excessive.
Replace brake chopper.
Ensure brake resistor is connected and not
damaged.
See parameter group 42 BRAKE
Check connection of brake acknowledgement
signal.
Check brakes.
Check resistor and resistor connection.
Check that resistance rating meets
specifications. See appropriate drive hardware
manual.
