6. FAULT CODES
In the event of a failure, the inverter switches off and a fault code appears on the 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
Overvoltage
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
Overcurrent
Check whether the motor power corresponds to the inverter power.
Check that the cable length limits have not been exceeded.
Check motor lead and motor for short-circuits and earth faults.
Check whether the motor parameters (P081 - P086) 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.
Increase the maximum motor frequency if a motor with high slip is used.
F005
Inverter overtemperature
(internal PTC)
Check that the ambient temperature is not too high.
Check that the air inlet and outlet are not obstructed.
Check that the integral fan is working.
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 / Parameter loss *
Check the entire parameter set. Set P009 to ‘ 0000’ before power down.
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 overtemperature by I
2
t
calculation
Check that the motor current does not exceed the value set in P083.
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 described in section 2.1 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 in section 5) or via the serial interface.
