On the ATV930 and other drives, would the torque measurement be affected by the presence of a sine wave filter between the drive and the motor?
Issue:
Torque Measurement when using Sine Wave Filters.
Product Line:
ATV630, ATV930, ATV71, ATV61, ATV320, ATV32, ATV312
Environment:
All
Cause:
NA
Resolution:
The torque measurement will not be affected by the presence of a sine wave filter between the drive and the motor. Actually, it makes torque measurement's value better.
The current scope will be actual SIN/COS wave with sine wave filter. Without sine wave filter, the output current will have some peak value, which probably affects the accuracy of current.
The torque is directly proportional to current (M∝I).
