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.
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
Set parameter No.2 according to the open to be used.
The MR-RB65, 66 and 67 are regenerative brake options that have encased the GRZG400-2 ,
GRZG400-1 and GRZG400-0.8 , respectively. When using any of these regenerative brake options,
make the same parameter setting as when using the GRZG400-2 , GRZG400-1
(supplied regenerative brake resistors or regenerative brake option is used with 11kW or more servo
amplifier).
