Description of the error
Values
Inspect the device causing the external error.
Inspect the presence of all 3 phases.
Internal error.
Troubleshooting to be done by the manufacturer.

necessary value or decreasing the load.
Increase the run-down time in menu item
32.StopM.
Decrease the load of the motor.
With power factor corrector in front of the
appliance:
▪ insert line choke in front of the appliance.
If occurs during the stopping process:
▪ increase the run-out time in menu item
32.StopM
▪ At device equipped with built-in ventilator
checking up of its rotation beyond 45C,
▪ at device built in cabinet checking up the
ventilation of the cabinet,
▪ checking up the extent of the loading of the
device.
Checking up the wiring and connections between
the device and the motor.
After acknowledgment of the error, if the
converter is in Stop state, try to set the
parameters once again.
Disconnect the converter from the line.
If the LEDs do not light anymore, the appliance
can be restarted.
