Issue:
IPR (motor power) parameter calculation
Product Line:
Altivar ATV61
Environment:
All
Cause:
IPr parameter
Resolution:
In order to calculate and/or monitor motor power, need to consider the speed of the motor, Power factor and efficiency.
The Power Factor and Efficiency drop at lower speeds.
Here are a couple of examples/calculations:
AH3 at 60hz: 96A x 460Vx sqrt(3) x 0.7(PF &Eff) = 53.54 kW
AH3 at 30hz: 35A x 230V x sqrt(3) x 0.43(PF & Eff) = 6.0 kW
Accuracy is about 10%
