Accumulated Power Consumption (APH)
Accumulated Power Consumption (APH)
Resolution:
The APH is calculated regarding motor electrical consumption measured by the drive to supply the motor ( motor current, motor voltage) so it includes mechanical losses.
The drive does not measure reactive power making the precision of the APH about 10%. The losses of the VSD are insignificant regarding this accuracy.
Please note it is not recommended to use the consumption power measurement APH for electrical billing for instance.
