Fault messages generated by the drive

Fault Cause
Drive IGBT temperature is excessive. Fault trip
ACS800 TEMP
limit is 100%.
(4210)
02.18 FW 1 bit 03
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
02.18 FW 1 bit 03
and y refers to phase (U, V, W).
BACKUP ERROR Failure when restoring PC stored backup of
drive parameters.
(FFA2)
BC OVERHEAT Brake chopper overload
(7114)
BC SHORT CIR Short circuit in brake chopper IGBT(s)
(7113)
BR BROKEN Brake resistor is not connected or it is
damaged.
(7110)
Resistance rating of brake resistor is too high.
BR OVERHEAT Brake resistor overload
(7112)
BR WIRING Wrong connection of brake resistor
(7111)
CHOKE OTEMP Excessive temperature of drive output filter.
Supervision is in use in step-up drives.
(FF82)
Fault tracing
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.
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.
Check resistor and resistor connection.
Check that resistance rating meets
specifications. See appropriate drive hardware
manual.
Let resistor 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.
Check resistor connection.
Ensure brake resistor is not damaged.
Let drive cool down.
Check ambient temperature.
Check filter fan rotates in correct direction and
air flows freely.
