Fault messages generated by the drive
Fault Cause What to Do
ACS800 TEMP
(4210)
02.18 FW 1 bit 03
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)
02.18 FW 1 bit 03
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.
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)
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)
Short circuit in brake chopper IGBT(s) Replace brake chopper.
Ensure brake resistor is connected and not
damaged.
BR BROKEN
(7110)
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.
BR OVERHEAT
(7112)
Brake resistor overload Let resistor 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.
BR WIRING
(7111)
Wrong connection of brake resistor Check resistor connection.
Ensure brake resistor is not damaged.
CHOKE OTEMP
(FF82)
Excessive temperature of drive output filter.
Supervision is in use in step-up drives.
Let drive cool down.
Check ambient temperature.
Check filter fan rotates in correct direction and
air flows freely.
