Cause
One of the three phases is missing from the power
supply
There is a voltage drop at the power supply
The environmental temperature is too high. When
the temperature is above 40°C (104°F) the inverter
will decrease its maximum output current
DC bus voltage exceed a threshold
Built in EEPROM has problems due to noise or
excessive temperature.
One of the three phases is missing from the power
supply
There is a voltage drop at the power supply
Unattended Start Protection active
The cable to the motor has been damaged
The motor has been damaged
Water have entered the motor
The power supply has got voltage transients
The internal temperature in the inverter is above
120°C (248°F). This could be caused by faulty ven-
tilation in the electrical cabinet.
The cable to the motor has been damaged
The motor has been damaged
Inspect the display on the inverter for any fault code
Inspect fuses inside electrical cabinet
Inspect the fuses in the worksites fuse box
Inspect cables
Measure that all three phases are present and at full
voltage at the cable end near the machine.
Make sure that the cable is not to long. If the cable
should be to long, use a cable with higher rating to a
distribution box nearer the machine.
Lower the speed
Inspect the tools
Change the tools if needed
Change the flexible spring steel discs
Correction
Inspect the fuses in the worksites fuse box
Inspect cables
Measure that all three phases are present and at
full voltage at the cable end near the machine
Make sure that the cable is not too long. If the
cable should be too long, use a cable with higher
rating to a distribution box nearer the machine
Inspect the ventilation fans
Inspect the filters to the fans
Inspect the power source
Check the fans/ let the motor drive cool down
