(d) MR-J3-11KT(4)-PX/LW MR-J3-15KT(4)-PX/LW MR-J3-22KT(4)-PX (when using the regenerative
option)
The MR-J3-11KT(4)-PX/LW MR-J3-15KT(4)-PX/LW MR-J3-22KT(4)-PX servo amplifiers are not
supplied with regenerative resistors. When using any of these servo amplifiers, always use the MR-
RB5E, 5R, 9P, 9F, 5K-4, 6B-4, 60-4, 6K-4 regenerative option.
The MR-RB5E, 5R, 9P, 9F, 5K-4, 6B-4, 60-4 and 6K-4 are regenerative options that have encased the
GRZG400-1.5 , GRZG400-0.9 , GRZG400-0.8 , GRZG400-0.6 , GRZG400-5.0 , GRZG400-2.5 ,
GRZG400-2.0 respectively. When using any of these regenerative options, make the same parameter
setting as when using the GRZG400-1.5 , GRZG400-0.9 , GRZG400-0.8 , GRZG400-0.6 ,
GRZG400-5.0 , GRZG400-2.5 , GRZG400-2.0 (supplied regenerative resistors or regenerative
option is used with 11k to 22kW servo amplifier).
Cooling the regenerative option with cooling fans improves regenerative capability.
The G3 and G4 terminals are for the thermal protector. G3-G4 is opened when the regenerative option
overheats abnormally.
