14. OPTIONS AND AUXILIARY EQUIPMENT
Inverse efficiency ( )
Capacitor charging (Ec)
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.
(3) Connection of the regenerative option
Set parameter No.0 according to the option to be used.
Parameter No.0
:Efficiency including some efficiencies of the servo motor and servo
amplifier when rated (regenerative) torque is generated at rated speed.
Since the efficiency varies with the speed and generated torque, allow for
about 10%.
:Energy charged into the electrolytic capacitor in the servo amplifier.

Selection of regenerative
0: Not used. (The built-in regenerative resistor is used. However, the MR-J2S-10CP
does not have a built-in regenerative resistor and therefore cannot use it.)
