11. OPTIONS AND AUXILIARY EQUIPMENT
(d) MR-J3-11KB(4)-PX to MR-J3-22KB(4)-PX (when using the regenerative option)
The MR-J3-11KB(4)-PX to MR-J3-22KB(4)-PX servo amplifiers are not supplied with regenerative
resistors. When using any of these servo amplifiers, always use the MR-RB5E, 9P, 9F, 6B-4, 60-4 and
6K-4 regenerative option.
The MR-RB5E, 9P, 9F, 6B-4, 60-4 and 6K-4 are regenerative options that have encased the GRZG400-
1.5 , GRZG400-0.9 , 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 , GRZG400-0.6 , GRZG400-5.0 , GRZG400-2.5 , GRZG400-2.0
(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 protector. G3-G4 is opened when the regenerative option
overheats abnormally.
