Fault messages generated by the drive
FAULT CAUSE WHAT TO DO
ACS800 TEMP
(4210)
3.05 FW 1 bit 3
Drive IGBT temperature is excessive. Fault trip
limit is 100%. Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against unit power.
ACS TEMP xx y
(4210)
3.05 FW 1 bit 3 and
4.01
Excessive internal temperature in inverter unit
of several parallel connected inverter modules.
xx (1...12) refers to inverter module number
and y refers to phase (U, V, W). Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against unit power.
AI < MIN FUNC
(8110)
3.06 FW 2 bit 10
(programmable
Fault Function
30.01 )
Analogue control signal is below minimum
allowed value due to incorrect signal level or
failure in control wiring. Check for proper analogue control signal
levels.
Check control wiring.
Check Fault Function parameters.
AP [message] Message generated by an EVENT block in the
Adaptive Program. Consult the documentation or author of the
Adaptive Program.
BACKUP ERROR
(FFA2) Failure when restoring PC stored backup of
drive parameters. Retry.
Check connections.
Check that parameters are compatible with
drive.
BC OVERHEAT
(7114)
3.17 FW 5 bit 4
Brake chopper overload Let chopper cool down.
Check parameter settings of resistor overload
protection function (see parameter group
27
BRAKE CHOPPER ).
Check that braking cycle meets allowed limits.
Check that drive supply AC voltage is not
excessive.
BC SHORT CIR
(7113)
3.17 FW 5 bit 2
Short circuit in brake chopper IGBT(s) Replace brake chopper.
Ensure brake resistor is connected and not
damaged.
BRAKE ACKN
(FF74)
3.15 FW 4 bit 3
Unexpected state of brake acknowledge signal See parameter group 42 BRAKE CONTROL .
Check connection of brake acknowledgement
signal.
BRAKE SLIP FLT
(FFF3)
3.33 CraneFW bit 3 The brake slipped and the motor speed
exceeded the motor slip speed
42.11 for a
period of slip fault delay 42.12 time.
Check brakes.
BR BROKEN
(7110)
3.17 FW 5 bit 0
Brake resistor is not connected or it is
damaged.
Resistance rating of brake resistor is too high. Check resistor and resistor connection.
Check that resistance rating meets
specifications. See appropriate drive hardware
manual.
