Err N° Failure Failure Name Explanation
326 Err CTE PU short circuit Short circuit on the RS485 communication connector.
Check for short circuit in the communication cable.
327 Err P24 24VDC short circuit Short circuit on the 24VDC power output (PC terminal).
Check for short circuit on the inverter control terminals.
328 Err MB1* Brake sequence
error 1
329 Err MB2* Brake sequence
error 2
330 Err MB3* Brake sequence
error 3
331 Err MB4* Brake sequence
error 4
332 Err MB5* Brake sequence
error 5
333 Err MB6* Brake sequence
error 6
334 Err MB7* Brake sequence
error 7
Sequence errors during use of the brake function.
335 Err FIN Heatsink overheat See detailed explanation below
336 Err OSD* Speed deviation
excess
Too big speed deviation during vector control
337 Err ECT* Encoder signal loss Problem with the encoder signal
338 Err E.1* Option
alarm(connector1)
339 Err E.2* Option
alarm(connector2)
340 Err E.3* Option
alarm(connector3)
Occurs if there is a contact fault of the connector between
the inverter and the communication option or if the
communication option is fitted to connector 1 or 2 or if the
switch of the plug-in option is not on the default setting.
341 Err ILF* Input phase failure 1 phase of the 3-ph input was lost for more than 1 second.
Repair the 3-phase power supply.
342 Err PTC PTC thermistor
operation
Overtemperature 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)
343 Err PE2 Parameter storage
error
Problem with parameter storage (EEPROM failure). If the
fault is persistent, replace the inverter.
344 Err CDO* Output Current
detection
Current exceeded the output current detection level
345 Err IOH Inrush overheat Resistor inrush current limit circuit overheated.
1) do not switch on/off the inverter frequently
2) Wait some time (15min) and try again
3) if the fault is persistent, replace the inverter
346 Err SER* Communication
error
Communication problem on the RS485 terminals
connector
347 Err AIE* Analog input error Overcurrent or overvoltage on input terminal 2/4
348 Err USB* USB communication
error
USB communication check time interval has elapsed
349 Err OS* Overspeed Speed exceeded the limit during encoder feedback control
350 Err OD* Position error Too big difference between the position command and the
position feedback during position control
