Published date: 10 March 2020

How do I calculate ATV320 OPR output power ?

Product Line:
Altivar 320



To calculate the value for OPR (motor power) in the ATV320 use formula 
Voltage * Current * Sqrt(3 * Power factor.
Voltatge and current can be viewed in the VFD  monitoring menu
The range of OPR is based on the rated motor power programmed in the unit.
The actual range is 0 to 2.5 X the rated motor power (NPR) within VFD settings.  
This would mean 100% would equal rated motor power (NPR).
