Fault s and alarms

A fault indicates a severe unfavorable state of the inverter. If a fault occurs, the inverter

is powered down with an OFF2 command and the LED "SF" on the Control Unit is

active. Faults must be acknowledged before the inverter can be switched on again.

An alarm states that the inverter is

● in a critical state that can lead to a fault (e.g. A0501 current limit)

● in an extraordinary temporarily state e.g. motor data identification

An alarm requires no reaction'

Fault

Cause

F00001

Overcurrent - Motor power does not

correspond to the inverter power

F00002

Overvoltage - mains supply voltage too high

or motor is in regenerative mode.

F00003

Undervoltage - mains supply has failed

F00004

Inverter over temperature - the inverter has

exceeded the temperature limits

F00005

Inverter overload

F00041

Motor data identification failure

F00052

Power stack failure

F00062

MMC contents invalid

F00070

PLC setpoint fault

F00071

USS setpoint fault

CU240E

Getting Started, 10/2007, A5E01301680B AA

Remedy

Check that the motor and inverter power

ratings are the same.

Check the mains supply voltage

Check mains supply

Check motor loading, pulse frequency

setting, ambient temperature or if fitted the

fan is working correctly.

Check motor power and load cycle

check that the motor is connected to the

inverter correctly and that the motor data

entered is correct.

Check the connections between the CU and

PM.

Recopy data to MMC and ensure that the

process is completed.

Check the value of P2040 and ensure it is

correct

Check and improve monitoring timing using
