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