What is the speed accuracy in percentage of the ATV930 drive when used with a closed loop encoder or when used in Sensorless Vector Control (SVC) in open loop?

Issue:
ATV930 drive:

• Percent of speed accuracy achievable with a closed loop encoder
• Speed regulation when used in open loop mode

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.
