Failure Message Overview
Error
Number Failure Failure Name Explanation
328 Err MB1* Brake sequence error 1 Sequence errors during use of the brake function.
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
335 Err FIN Heatsink overheat Refer to Failure 335: FIN-Error (COOLING FIN INVERTER
OVERHEAT).
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) Occurs if there is a contact fault of the connector between the in-
verter and the communication option or if the communication op-
tion is fitted to connector 1 or 2 or if the switch of the plug-in
option is not on the default setting.
339 Err E.2* Option alarm (connector2)
340 Err E.3* Option alarm (connector3)
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. Refer to 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 approximately 15 minutes 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.
