How does ATV320 calculate OPR output power ?

Product Line:
Altivar 320

Environment:
All model numbers, all serial numbers

Cause:
N/A

Resolution: 
To calculate the value for OPR (motor power), the ATV320 uses this formula:
Voltage * Current * Sqrt(3) * Power factor.
Voltage and current can be viewed in the VFD  monitoring menu.
The OPR value is based on the rated motor power programmed in the unit and has a range of 0 to 2.5 X the rated motor power (NPR) value.  This means 100% equals rated motor power (NPR).
