What does E03 Mean on Hitachi SJ200?Looking for some help with some Hitachi SJ200 Errors. I'm not sure if you call these errors, faults, or alarms but I can use some detailed info and troubleshooting suggestions.
- Hitachi E03 Alarm
- Hitachi E03 Error
- Hitachi E03 Fault
Thanks in advance!
E03 Error / E03 Fault / E03 Alarm
Means: Overcurrent during "acceleration"
Possible Causes: Inverter output was short-circuited, or the motor shaft is locked, or the load is too heavy, or a dual-voltage motor is wired incorrectly.
Note: The Hitachi SJ200 will over current trip at nominally 200% of rated current.
Also, Hitachi SJ200 inverters will trip on over-current to protect the inverter. The motor output turns OFF, hence the motor free-wheels to a stop. Just press the Stop/Reset key to reset the inverter and clear the error.
