Watchdog Trip
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.

Slip limit exceeded
005
Inverter overtemperature (heatsink)
006
Motor over-temperature
010
15V power supply - current limit

7. FAULT AND WARNING CODES
Corrective Action
Parameterise fixed frequency(ies) on the digital inputs.
Set parameter P012 < P013.
Change the settings of digital inputs P051 to P055 and P356.
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.
Change parameter P006 and / or P201
Set parameter P211 < P212.
See F002
Remove prime power and re-apply
Corrective Action
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.
Increase ramp time or fit breaking resistor
Check that motor is not overloaded, check motor parameters
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 if motor is overloaded.
Check that P087 has not been set to 1 without a PTC being connected.
Check Connections
WARNING: The inverter may start at any time.
