Hello!

I have 2.2 kW 3-phase SINAMICS G120 converter (CU250S-2 PN 6SL3246-0BA22-1FA0 + PM240-2 6SL3210-1PE16-1AL1) and 0.12 kW asynchronous motor (1LA7060-4AB10-Z). I want to make on-desk stand with this equipment, but 3-phase socket is located far enought. I tried to feed converter from 1-phase socket, connecting phase to L1 and neutral to L2. When converter connected  this way DC bus voltage is about 300 VDC. It's enougth to run my motor in delta connection. But when I try to start motor, I have F07802. I failed to change p0210 "Drive unit line supply voltage" to 290V  because it can not be lower than 380V for 3-phase power modules, and I failed to disable  F07802 using p2118 and p2119, p2118[0] just not changing to 7802. Is it way to power G120 with 3-phase PM  from one phase exists?

The error cannot be cleared because the undervoltage in the intermediate circuit is caused by hardware.
