Corrective Action
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.
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.
Set parameter P211 < P212.
Check motor cable and motor for short-circuits and earth
faults.
