Fault Codes
In the event of a failure, the inverter switches off and a fault code can be viewed on the OPm2 display. The last fault that occurred is
stored in parameter P930. e.g. ‘0003’ indicates that the last error was F003.
Fault Code Cause Corrective Action
F001 Over voltage Check whether supply voltage is within the limits indicated on the rating plate.
Increase the ramp down time (P003).
Check whether the required braking power is within the specified limits.
F002 Over current Check whether the motor power corresponds to the inverter power.
Check the motor for short-circuits and earth faults.
Check whether the motor parameters (P081 - P085) correspond with the motor
being used.
Check the stator resistance (P089).
Increase the ramp-up time (P002).
Reduce the boost set in P078 and P079.
Check whether the motor is obstructed or overloaded.
F003 Overload Check whether the motor is overloaded.
F005 Inverter over temperature Check that the ambient temperature is not too high.
(internal PTC) Check that the air inlet and outlet are not obstructed.
F008 USS protocol timeout Check the serial interface.
Check the settings of the bus master and P091 - P093.
Check whether the timeout interval is too short (P093).
F010 Initialisation fault/ Check the entire parameter set. Set P009 to ‘0000’ before power down.
Parameter loss*
F011 Internal interface fault* Switch off power and switch on again.
F012 External trip (PTC) Check if motor is overloaded.
F013 Programme fault* Switch off power and switch on again.
F018 Auto-restart after fault Automatic re-start after fault (P018) is pending.
WARNING: The inverter may start at any time.
F030 PROFIBUS link failure Check the integrity of the link.
F031 Option module to link failure Check the integrity of the link.
F033 PROFIBUS configuration error Check the PROFIBUS configuration.
F036 PROFIBUS module watchdog
trip
Replace PROFIBUS module.
F074 Motor over temperature Check that the motor current does not exceed the value set in P083.
by I 2 t calculation
F106 Parameter fault P006 Parameterise fixed frequency(ies) and/or motor potentiometer on the digital
inputs.
F112 Parameter fault P012/P013 Set parameter P012 < P013.
F151-F153 Digital input parameter fault Check the settings of digital inputs P051 to P053.
F188 Automatic calibration failure Motor not connected to inverter - connect motor.
If the fault persists, set P088 = 0 and then enter the stator resistance of the
motor into P089 manually.
F201 P006 = 1 while P201 = 2 Change parameter P006 and/or P201.
F212 Parameter fault P211/P212 Set parameter P211 < P212.
* Ensure that the wiring guidelines to minimise the effects of EMI have been complied with.
When the fault has been corrected the inverter can be reset. To do this press button P twice (once to display P000 and the second
time to reset the fault), or erase the fault via a binary input (see parameters P051 - P053) or via the serial interface.
