1) Reload the Frequency Inverter Parameters.
2) If the fault is persistent, replace the Frequency Inverter.

Failure Name Failure Name:
Sequence errors during use of the brake function.
See detailed explanation below.
Too much speed deviation during vector control
Problem with the encoder signal
Occurs if there is a contact fault of the connector between
the Frequency Inverter and the communication device or if the
communication device is fitted to connector 1 or 2 or if the
switch on the plug-in device is not on its default setting.
1 phase of the 3-phase input was lost for more than 1 second.
Correct the 3-phase power supply.
Over-temperature of motor PTC (switch AU/PTC must be on PTC)
1) Check if motor cooling fan (if present) functions normally
2) Check for contact faults in the wiring (see electrical scheme)
Problem with parameter storage (EEPROM failure). If the fault is
persistent, replace the Frequency Inverter.
Current exceeded the output current detection level.
Resistor in-rush current limit-circuit overheated.
1) Do not switch the Frequency Inverter on an off quickly.
2) Wait some time (15 min) and try again.
3) If the fault is persistent, replace the Frequency Inverter.
Communication problem on the RS485 terminal-connector.
Overcurrent or overvoltage on input terminal 2/4.
USB communication check-time interval has elapsed.
Speed exceeded the limit during encoder feedback control.
Too much difference between the position command and the
position feedback during position control.
Rotation command is different from the actual motor rotation direction.
Rotation direction of the speed command is different from the
estimated speed, causing overload.
Problem with an internal circuit; replace the Frequency Inverter.
