Check whether the supply voltage is within the limits indicated on the
rating plate.
Increase the ramp-down time (P003) or apply a braking resistor (option).
Check whether the required braking power is within the specified limits.
Check that motor power corresponds to variable speed drive 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.
Check whether the motor is overloaded.
Increase the maximum motor frequency if a motor with high slip is used.
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.
Check that the ambient temperature is not too high.
Check that the air inlet and outlet are not obstructed.
Check that the variable speed drive's integral fan is working.
Check the serial interface.
Check the settings of the bus master and P091 – P093.
Check that the variable speed drive's integral fan is working.
Check the entire parameter set. Set P119 to "0000" before power down.
Switch off power and switch back on again.
The source of the trip is a digital input (configured as an external trip input)
going low. Check the external source.
Switch off power and switch back on again.
Ensure that P080 – P085 correspond to the name plate motor details.
Adjust P386. Note that a flying restart does not work with multi-motors.
Trip occurs only if P074 = 4, 5, 6 or 7. Check that the motor current does
not exceed the values set in P083 and P086.
Parameterise fixed frequency(ies) on the digital inputs.
Motor not connected to variable speed drive – connect motor. If fault
persists, set P088 = 0 and then enter the measured stator resistance of
the motor in P089 manually.
Set parameter P211 < P212
Check motor cable and motor for short-circuits and earth faults.
