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
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) or apply braking resistor (option).
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 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.
F003
Overload
Check whether the motor is overloaded.
Increase the maximum motor frequency if a motor with high slip is used.
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 heatsink sensor)
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).
F009
Undervoltage
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.
F010
Initialisation fault
Check the entire parameter set. Set P009 to `0000' before power down.
F011
Internal interface fault
1
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
1
Switch off power and switch on again.
F016
Sensorless vector control unstable
Try calibrating the stator resistance (set P088 to 1 and RUN).
Alternatively try re-adjusting the sensorless vector control loop gain (see
P386).
F030
PROFIBUS link failure
Check the integrity of the link.
F031
PROFIBUS to inverter link failure
Check the integrity of the link.
F033
PROFIBUS configuration error
Check the PROFIBUS configuration.
F036
PROFIBUS module watchdog trip
Replace PROFIBUS module
F057
Delayed Trip (See P057)
P051 to P055 or P356 = 20 and trip input has remained low for longer than
the time set in P057
F074
Motor overtemperature by I
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.
F075
Over current during ramping down
Increase the ramp down time (P003).
F101
Internal interface fault
1
Switch off power and switch on again.
F105
Inverter overtemperature (internal
sensor)
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
