Dear Friend
I realy needs your help , I have Alstom DC excitation system with VNTC/WNTC+MD29 drive ,we codnt working with Automatic PF correction mode
because we didnt have programming code , but its working normally with mounal mode throgh veriable resistance , I suggested to us ML1400 PLC with analog output instead of veriable resistance for auto-correction PF using Cosphy signal 0..10V as feedback analog input to reach the Motor to desired PF (0.9)
Any help will be highly appresiated
Best Regards
Ali
