What does E09 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 E09 Alarm
• Hitachi E09 Error
• Hitachi E09 Fault

Thanks in advance!

E09 Error / E09 Fault / E09 Alarm

Means: Undervoltage Error (Under-Voltage Fault)

Possible Cause: DC bus voltage decreased enough to cause a control circuit fault.

Also, Hitachi SJ200 inverters will trip on under-voltage to protect the drive. 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.
