13. OPTIONS AND AUXILIARY EQUIPMENT

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 brake option.

ER [J] Es Ec

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

(3)Connection of the regenerative brake option

When using the regenerative brake option, always remove wiring from across P-D and install the regenerative brake option across P-C. Set parameter No.0 according to the option to be used. The regenerative brake option will generate heat of about 100. Fully examine heat dissipation, installation position, used cables, etc. before installing the option. For wiring, use flame-resistant cables and keep them clear of the regenerative brake option body. Always use twisted cables of max. 5m length for connection with the servo amplifier.
