What does E07 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 E07 Alarm
- Hitachi E07 Error
- Hitachi E07 Fault
Thanks in advance!
E07 Error / E07 Fault / E07 Alarm
Means: Overvoltage Protection
Possible Cause: DC bus voltage exceeds a threshold, due to regenerative energy from motor.
Also, Hitachi SJ200 inverters will trip on over-voltage 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 drive and clear the error.
