7. FAULT AND WARNING CODES
7.1 Fault Codes
In the event of a fault, the inverter switches off and a fault code appears on the display. The last fault that occurred is stored in
parameter P140, the preceding faults in P141 - P143.. e.g. '0004' indicates that the last fault was F004

Corrective Action
Check whether supply voltage is within the limits indicated on the rating
plate.
Increase the Ramp-down time (P003) or apply braking resistor (option).
Check whether the required braking power is within the specified limits.
Check whether the motor power corresponds to the inverter power.
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 (P080 - 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.
Check whether the motor is overloaded.
Increase the maximum motor frequency if a motor with high slip is used.
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.
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
Check the serial interface.
Check the settings of the bus master and P091 - P093.
Check whether the time-out interval is too short (P093).
Check whether the supply voltage is within the limits indicated on the rating
plate.
Check the supply is not subject to temporary failures or voltage reductions.
Check the entire parameter set. Set P009 to `0000' before power down.
Switch off power and switch on again.
1
Source of trip is digital input (configured as an external trip input) going low
- check the external source.
Switch off power and switch on again.
1
Try calibrating the stator resistance (set P088 to 1 and RUN).
Alternatively try re-adjusting the sensorless vector control loop gain (see
P386).
Check the integrity of the link.
Check the integrity of the link.
Check the PROFIBUS configuration.
Replace PROFIBUS module
P051 to P055 or P356 = 20 and trip input has remained low for longer than
the time set in P057
Trip occurs only if P074 = 4, 5, 6 or 7. Check that the motor current does
t
2
not exceed the value set in P083 and P086.
Increase the ramp down time (P003).
Switch off power and switch on again.
1
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
