4 636675kw drive operated motor current fluctuation from(85-130)ampere.current setting in drive is 130amp.sometimes motor trip when current limit cross 130amps.I change the drive. still current fluctuate between 80-130amps but in this time motor not trip,current setting in drive is 130amps.where is the problem?
