CODE MEANING
1
Wrong Config
Cause: EEPROM memory not configured.
Solution: Contact after‑sales service.
8
Watch Dog
Cause: Inverter cannot start or stop electric motor.
Solution: Check connections and continuity of electric motor. If OK, replace inver‑
ter.
13
Eeprom KO
Cause: EEPROM hardware or software problem.
Solution: Replace inverter.
16
Aux output KO
Cause: Problem with electromechanical brake.
Solution: This is generally a temporary problem due to certain working conditions.
If problem persists, replace inverter.
17
Logic failure #3
Cause: Activated in the event of high inverter current peaks.
Solution: This is generally a temporary problem due to certain working conditions.
If problem persists, replace inverter.
18
Logic Failure #2
Cause: Internal fault in the inverter.
Solution: Replace inverter.
19
Logic failure #1
Cause: Sudden voltage surge or voltage drop.
Solution: This is a temporary problem due to certain working conditions. If pro‑
blem persists, replace inverter.
30
VMN low
Cause: Inverter power supply voltage is lower than battery voltage, or alternatively
incorrect connection to positive battery pole.
Solution: Check connection to positive battery pole. If problem persists, replace
inverter.
31
VMN High
Cause: One motor phase not connected correctly or faulty.
Solution: Check motor phases. If problem persists, replace inverter.
