FAULT CODES .................................................................
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)
F002 Overcurrent Check whether the motor is obstructed or overloaded
Check whether the motor power corresponds to the inverter power
Increase the ramp-up time (P002)
Check that the cable length limits have not been exceeded
Check motor cable and 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)
Reduce the boost set in P079
F003 Overload Check whether motor is overloaded
F004 Overheating of motor
(monitoring with PTC)
Check if motor is overloaded
Check the connections to the PTC
Check that P087 has not been set to 1 without a PTC being
connected
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 inverter’s integral fan is working
F008 USS protocol time-out Check the serial interface
Check the settings of the bus master and P091-P093
Check whether the time-out interval is too short (P093)
F010 Initialisation fault Check the entire parameter set. Set P199 to ‘0000’ before power
down
F011 Internal interface fault Switch off power and switch on again
F012 External trip Source of trip is digital input (configured as an external trip input)
going low - check the external source
F013 Programme fault Switch off power and switch on again
F016 Start on Fly Check that the motor name plate data (P081 to P085) is correct
Disable then enable P016 again
F074 Motor overtemperature by l
2
t
calculation
Trip occurs only if P074 = 4,5,6 or 7. Check that the motor current
does not exceed the value set in P083 and P086
F106 Parameter fault P006 Parameterise fixed frequency(ies) on the digital inputs
F112 Parameter fault P012/P013 Set parameter P012 < P013
F151-156 Digital input parameter fault Change the settings of digital inputs P051 to P055 and P0356
F188 Automatic calibration failure Motor not connected to inverter - connect motor
If the fault persists, set P088 = 0 and enter the measured stator
resistance of the motor into P089 manually
F212 Parameter fault P211/P212 Set parameter P211 < P212
F231 Output current measurement
imbalance
Check motor cable and motor for short-circuits and earth faults
