Hello,
We have a strange behavior on powerflex 525 drive running a blade with v belts attached to the motor .The drive only shows accelerating and does not reach set speed. Current limit is ok. Strange thing is when I only run the drive with out the load it vfd reaches the speed. When we give the blade a gentle push with hand it accelerates and reaches set speed. What could be the reason
