Asking about AB Softstarter
Motion control, servos, steppers, etc. topic
Posted by mohammed abdelsttar on 2 October, 2007 - 10:57 pm
I have AB softstarter 180A, 380VAC. When I connected it to a 90KW motor it worked good on high speed, but on low speed it had a fault message (FAULT 41.LOSS PHASE). Although I connected the power terminal very good, where is the problem?
