Hello All,
I am in need of help for the problem that I had with Powerflex700 Drive. Here is the situation
First, I enabled the flying start (P169=1). I start the VFD and it ramp up to the commanded frequency. When i send a stop command, the VFD will stop. Again, if i re-send the start command while motor coasting down, the VFD couldn't ramp from the current motor rotation and instead it ramp from 0 rpm, which give me high current motor overload alarm.
Drive Information: 20BD077-A3ANNANA0
Motor: 30HP
sw version: 3.002
Does anyone experience this before? Any suggestion is deeply appreciated. Thanks
