Reversing Star Delta Starter
Hello everyone,
I have acquired a used Milling Machine in need of a retrofit all wiring has been removed.
For this purpose I have a siemens Logo 0BA6 I intend to use with Hardware interlocking Contactors. The controls I would like are Start, Stop, Forward, Reverse, Low Speed, High Speed. Hardwired Safety isolator.
The 3 phase 0.85/1.1KW 1430/2850rpm two speed motor, has the markings U1,U2,V1,V2,W 1,W2.
I need some help with the interlocking logic, I can find many Ladder logic examples of basic start and stop with interlocks, But I don’t find any reversing a motor with dual speed, I think its by using U1,V1,W1 as one speed and U2,V2,W2 as the other.
Any help welcome.
