6. FAULT MESSAGES. DESCRIPTION AND
ACTIONS
FAULT TRIPS
When a fault occurs, the VS65 will stop the motor and will display the fault that caused the trip. The red
LED and fault message will remain until the fault has been removed and the soft starter is reset.
Fault F0 NO FAULTS
Description No fault detected.
Possible Cause Normal operation.
Action None required.
Fault F1 PHA MISING
Description Supply phase loss.
Possible Cause Loss of phase, fuse failure, cable fault, motor winding fault.
Action Check supply, all cables including thyristors, and motor. If the problem
persists, call Power Electronics or an authorised distributor.
Fault F2 WRONG PH / SQ
Description Incorrect input supply phase sequence.
Possible Cause The mains phase sequence doesn't correspond to G3.1 (1 PHASE SEQUEN=2)
Action Swap two input phase over or change G3.1 Phase Sequence to suit supply
phase sequence.
Fault F3 ASYM CURR
Description Phase current imbalance.
Possible Cause There is a current imbalance higher than 40%.
Action Check the motor; check the load and the coupling between both. Check input
power supply is always balanced. Check thyristors. If the problem persists, call
Power Electronics or an authorised distributor.
Fault F4 OVERLOAD.
Description Calculated motor overload has reached an unacceptable level.
Possible Cause Motor overload. If the trip is produced during start, it could be a mechanical
problem. If it occurs when the motor is running at nominal speed, probable
causes could be a wrong setting at G.3.2. screen or a change of the load
conditions.
Wrong nameplate values.
Action Check that current from the G3.2 screen is the same as the motor. Check
working conditions and connections of motor. Check load. Check nameplates.
.
Fault F5 UNDERLOAD.
Description Motor under load.
Possible Cause Motor current draw is lower than that set in G3.6 screen. Soft starter has been
working during for longer than the one set in G3.7 screen.
Motor working with no load.
Wrong setting of under load conditions.
Action Check that mechanical parts coupled to the motor are ok and that the motor is
not working unloaded. In case of pump application, check there is no air inside
the pipe network and that the pump suction is not obstructed. Wrong adjustment,
set again under load settings G3.6 and G3.7.
