Would you care to elaborate more on why the Drive might detect a ground fault if you connect it to a de-energized or partially de-energized motor?
Thanks.

As first An earthfault could have many possibilities E.g. a defect in the inverter output, a bad cable connection, a defect cable or motor isolation, etc. Also it is not possible to use a contactor / MCCB / isolating switch etc. on the inverter output (see https://support.industry.siemens.com/cs/ww/en/view/1017401 ) If you need to stop the Motor, you have to do it by using OFF1 / OFF2 or OFF3 of the inverter. With one of this OFF the inverter output is de energized. If you need to switch off the power supply, you have to do it on the inverter input (after switch OFF1 the inverter) If you need to control more than one motor on one inverter, please see https://support.industry.siemens.com/cs/ww/en/view/14390055 |
