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.
ER [J] =
η
m
• Es - Ec
Calculate the power consumption of the regenerative option on the basis of single-cycle operation
period tf [s] to select the necessary regenerative option.
PR [W] = ER/tf
