Fault Code
Cause
Corrective Action
F106
Parameter fault P006
Parameterise fixed frequency(ies) on the digital inputs.
F112
Parameter fault P012/P013
Set parameter P012 < P013.
F151-
F156
Digital input parameter fault
Change the settings of digital inputs P051 to P055 and P356.
F188
Automatic calibration failure
Motor not connected to inverter - connect motor.
If the fault persists, set P088 = 0 and then enter the measured 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.
F231
Output current measurement
imbalance
See F002
F255
Watchdog Trip
Remove prime power and re-apply
1
Ensure that the wiring guidelines described in section 1.2 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 clear the fault via a binary input
(see parameters P051 - P055 and P356 in section 6)
.
7.2
Warning Codes
In the event of a warning, the inverter display will flash. The last warning to occur is stored in parameter P931.
Warning Code Cause
Corrective Action
002
Current limit active
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.
003
Voltage limit active
Increase ramp time or fit breaking resistor
004
Slip limit exceeded
Check that motor is not overloaded, check motor parameters
005
Inverter overtemperature (heatsink)
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
006
Motor over-temperature
Check if motor is overloaded.
Check that P087 has not been set to 1 without a PTC being connected.
010
15V power supply - current limit
Check Connections
018
Auto re-start after fault (P018) is
pending
WARNING: The inverter may start at any time.
075
Braking resistor - hot
