VS65 SERIES MV SOFT STARTER
POWER ELECTRONICS
36
FAULT MESSAGES
Fault F6 PEAK CURR
Description VS65 peak current output exceeded. The current is higher than six times
nominal.
Sense level (6xIn). VS65 Rated Current.
Possible Cause Rotor locked. Short circuit in output circuit. VS65 current transformers failure.
Torque pulse setting too high.
Action Check cables and motor. Reduce Torque pulse setting.
If the problem persists, call Power Electronics or an authorised distributor.
Fault F7 STARTER OT
Description Heat sink too hot (>85ºC).
Sense level (> 85°C).
Possible Cause Insufficient cooling.
Fan failure.
Ambient temperature too high (>45ºC).
The actual current is higher than the nominal.
Action Check fans and cooling paths. Check the ambient temperature during normal
operation doesn't exceed 45ºC or 50ºC with re-rating. Check that correct re-rating
has been applied if higher than 45ºC. Check that actual motor current is the same
or smaller than the VS65 nominal current.
Fault F8 MOTOR PTC .
Description Not used for this soft starter.
Fault F9 SHEARPIN
Description Shearpin current trip.
Sense level G3.8 Shearpin Current.
Possible Cause The motor has drawn a higher current than Shearpin protection setting at G3.8.
Rotor locked due to a mechanical obstruction.
Action Check if it’s possible that motor reaches the Shearpin current under normal
operation, and if so, increase the value of that protection. Check motor, cables
and load and the reason of the over current.
Fault F10 OVER VOLT
Description High supply voltage for too long period.
Sense level The combination of parameters G3.12 OVERVOLTAGE and G3.13
OVERVOLTAGE DELAY.
Possible Cause Fluctuating power supply, wrong settings; the input voltage of each phase in
parameter G3.12; and the time set in G3.13.
Action Check supply voltage and set G3.12 and G3.13. Check supply.
Fault F11 UNDER VOLT
Description Low voltage supply for too long period.
Sense level The combination of parameters G3.10 UNDERVOLTAGE and G3.11
UNDERVOLTAGE DELAY.
Possible Cause Impedance of input power supply is too high. Excess current draw, weak supply.
Check the input voltage of each phase is higher than G3.10 parameter and
during the time set in G3.11 parameter.
Action Check supply, check values at G3.10 and G3.11. Check supply.
