Hello Colleagues,
I`m facing some problem with my new Powerflex 753, seems after sometime running, i try start the motor again and i have the message fault "short U/V", it happens with different motors i tried, the drive is not the problem, seems some parameter need to be changed or its to much sensitive.
I already have tried change the motors, and its running fine for sometime but later the fault back, it happens with different units also, I have 4 in the total, but just 2 have this small problem.
the motors and cables was tested many times, also it was replaced, but seems nothing really fix the problem.
Any ideas about this issue?
