Losses of servo motor and servo amplifier in regenerative mode
The following table lists the efficiencies and other data of the servo motor and servo amplifier in the regenerative mode.
Inverse efficiency ( η
m
): Efficiency including some efficiencies of the servo motor and servo amplifier when rated (regenerative)
torque is generated at rated speed. Efficiency varies with the speed and generated torque. Since the characteristics of the
electrolytic capacitor change with time, allow for approximately 10% higher inverse efficiency.
Capacitor charging (Ec): Energy charged into the electrolytic capacitor in the servo amplifier
Subtract the capacitor charging from the result of multiplying the sum total of regenerative energies by the inverse efficiency to
calculate the energy consumed by the regenerative option.

Calculate the power consumption of the regenerative option on the basis of single-cycle operation period tf [s] to select the
necessary regenerative option.
