PR(W)
Calculate the total of energies at each timing. Only when the total is negative (timings 3), 4) in
the example), use the following expression for calculation.
Energy total ER
If the subtraction results are negative at all timings, the regenerative brake option is not
needed. From the total of ER's whose subtraction results are positive and a single-cycle period,
the power consumption of the regenerative brake option can be calculated with the following
expression.
