I think mostly correct, except forI just want to confirm this is the motors internal diagram.
I just wanted to confirm the working of the wiring as following we have three mutually exclusive ways of motor operation.
- The motors U1-V1-W1 windings energized by Contactor 161k07.
- The motors U1-V1-W1 windings energized by Hybrid motor starter 160k10.
- The motors U2-V2-W2 windings energized by 161k04 contactor and while this is done its auxiliary contacts shorts the windings U1-V1-W1.
