Err N° Failure Failure Name Explanation
314 Err PE Corrupt memory Memory was overwritten too many times. Replace inverter.
315 Err PUE PU leave out See detailed explanation below
316 Err Ret* Retry no over The max number of retries after fault reached.
The actual inverter error code that causes the problem and
which should be solved, is stored just before Err 316 in the
error log.
317 Err CPU CPU Fault Communication error of built in CPU. Replace inverter
318 Err E.6 CPU Fault 6 Internal fault, If the fault is persistent, replace the inverter
319 Err E.7 CPU Fault 7 Internal fault, If the fault is persistent, replace the inverter
320 Err IPF Instantaneous
power failure
Power failure between 15 and 100ms. Check for bad
contacts in the power circuit. Repair the power supply.
321 Err UVT Under voltage Supply voltage too low. Check jumper P/+-P1.
322 Err LF Output phase
failure
Phase open detected on inverter output. Check for bad
contacts or defect (open) motor windings.
323 Err OP1* Option slot 1 Problem with the option in slot 1 or option contact fault
324 Err OP2* Option slot 2 Problem with the option in slot 2 or option contact fault
325 Err OP3* Option slot 3 Problem with the option in slot 3 or option contact fault
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.

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 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)
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.
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.
