Issue:
ATV930 drive:
Product Line:
ATV930 drives
Environment:
Closed Loop encoder
Cause:
Speed Accuracy / Speed Regulation
Resolution:
For ATV930 drive,
The AC Drive shall provide a speed accuracy 0.01 % of the nominal speed of the motor, in closed-loop mode, with an encoder.
The drive has a speed accuracy within 5% of the nominal motor slip when operating in open loop sensorless vector mode.
