7. Protections and alarms
Anytime a protection occurs a blinking message is displayed together with an audible alarm; on STATUS in the initial view, the
protection is displayed; by pressing the STOP button. Only from this position (STATUS) in the initial view is it possible to try
to reset the alarm; if IPFC does not reset the alarm it is displayed again together an audible sound.
ALARM MESSAGE ALARM DESCRIPTION POSSIBILE SOLUTIONS
OVERCURRENT MOT.
Motor overload: input current of the
motor is higher than the rated motor
current setting parameter.
Motor voltage drop caused by the inverter
causes the motor input current to be
higher than rated. Contact motor
manufacturer to check if motor is capable
of accepting this current.

Make sure that the motor current setting
parameter is higher than rated.

Check other possible causes of over current
UNDER VOLTAGE
Supply voltage too low
Check possible causes of undervoltage
OVER VOLTAGE
Supply voltage too high
Check possible causes of overvoltage
OVER TEMP. INV.
Inverter over temperature

Make sure than ambient temperature is
less than 40 °C (104 °F).

Check if auxiliary cooling fan is working
properly and if mounting space is adequate
for proper cooling.

Reduce the PWM value (Advance
Parameter Menu)
NO LOAD
No load

Check if load is properly connected to the
IPFC terminals
