I am controlling the powerflex 527 drive with MSO instruction, first setting the drive on and then running the motor with MAJ instruction. After MSO instruction, motor is rotating about 2 sec and then stops to wait the MAJ. I have not find any solution for this. My configuration is frequency control, no feedback, sensorless.
One hint i found from the rockwell pages but it did not help me. Rated slip speed is set to zero.
