Dear All,
We are trying to understand the abnormal behavior of the above drive but we cannot find any reason for it. on load condition there is a very strong electrical humming sound in the motor. we have worked through the power section of the drive and change IGBT's a lot of time but still the problem is not solved we have also changed the sync board but failed. Master drive is in master slave configuration our motor is double delta. separately wind. There is a twice a difference in current of master and slave drive. the Master side is on higher side.
we want to know in normal condition the current of master and slave drive should be equal or differ? If it differ , how much it differ to each other.?
