Diagnostics
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
