DESCRIPTION
1
Wrong Config
Cause - EEPROM memory not configured.
Solution - Contact Hinowa 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 inverter.
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 condi-
tions. If problem 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.
37
Contactor closed
Cause – Relay remains closed when power to coil is disconnected.
Solution – Check relay.
38
Contactor Open
Cause – Inverter supplies power to relay coil but contact doesnft close.
Solution – Check relay and power supply to coil.
49
I=0 Ever
Cause – Feedback current from motor sensor not constantly at 0.
Solution – Check connection to motor.
