13. OPTIONS AND AUXILIARY EQUIPMENT
(d) MR-J2S-11KA-PX to MR-J2S-22KA-PX (when using the regenerative brake option)
The MR-J2S-11KA-PX to MR-J2S-22KA-PX servo amplifiers are not supplied with regenerative
brake resistors. When using any of these servo amplifiers, always use the MR-RB65, 66 or 67
regenerative brake option.
The MR-RB65, 66 and 67 are regenerative brake options that have encased the GRZG400-2 Ω ,
GRZG400-1 Ω and GRZG400-0.8 Ω , respectively. When using any of these regenerative brake
options, make the same parameter setting as when using the GRZG400-2 Ω , GRZG400-1 Ω or
GRZG400-0.8 Ω (supplied regenerative brake resistors or regenerative brake option is used with
11kW or more servo amplifier).
Cooling the regenerative brake option with fans improves regenerative capability.
The G3 and G4 terminals are for the thermal sensor. G3-G4 are opened when the regenerative
brake option overheats abnormally.
