14 DL850/DL850V Real Time Math Application Three-phase inverter power calculation (Power) <Application Overview> Thanks to its multi-channel measurements and calculation capabilities, a three-phase inverter power (Σ) can be calculated in real time by the DL850. The line voltage(u1, U2) and phase current(i1, I2) can be measured, then the instantaneous power (multiplication) can be calculated simultaneously and displayed as a waveform. Using the Poly-Add-Sub formula, each (single-phase) instantaneous power can be summed in order for the three-phase power to be calculated in real time. Moreover, the DL850 can also calculate RMS value in real time. In Inverter driver Out An active power per cycle can be calculated using the real time math formula Power.

An excess current and/or temperature increase may be occurred when the performance has been declined. Using the DL850/DL850V, the power waveform (trend) at motor starting-up can be calculated and displayed in real time.

On the other hand, it may be difficult to do so by only monitoring its waveform, because a wide variety of frequency components are complicatedly superimposed. In such a case, it can be evaluated as vibration energy by calculating the RMS per time.

The mechanical (rotary) angle can be measured preciselyby encoder signals, whereasthe input current waveform contains harmonics and it is distorted. Consequently, the phase difference between the input current and the rotary angle can not be identified easily. The Electrical Angle operation enables to extract the fundamental component of current by Discrete Fourier Transform, then calculate the phase difference between it and the rotary angle in real time.
