Warning Codes
In the event of a warning, the inverter display will flash. The last warning to occur is stored in parameter P931.
Warning 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 start up time (P002).
Reduce the boost set in P078 and P079.
Check whether the motor is obstructed or overloaded.
003 Voltage slip active
004 Slip limit exceeded.
005 Inverter overtemperature Check that the ambient temperature is not too high.
(heatsink) Check that the air inlet and outlet are not obstructed.
Check that the inters 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 Use power supply- current limit
018 Auto re-start after fault (P018)
is pending
WARNING: The inverter may start at any time.
075 Braking resistor-hot
System Parameters
Note: In the following parameter table:
l
Indicates parameters that can be changed during operation.
¶¶¶
Indicates that the value of this factory setting depends on the rating of the inverter.
If parameters are changed accidentally, all parameters can be reset to their default values by setting parameter P944 to 1 and
then pressing P.
