[Appendix 1] Summary of MR-J4_B_-RJ020 + MR-J4-T20

(4) MR-J4-11KB-RZ020 to MR-J4-22KB-RZ020 and MR-J4-11KB4-RZ020 to MR-J4-22KB4-RZ020 (when
regenerative options are used.)
MR-J4-11KB-RZ020 to MR-J4-22KB-RZ020 and MR-J4-11KB4-RZ020 to MR-J4-22KB4-RZ020 do not
come with regenerative resistors. When you use these servo amplifiers, be sure to use MR-RB5E, MR-
RB5R, MR-RB9P, MR-RB9F, MR-RB9T, MR-RB5K-4, MR-RB6B-4, MR-RB60-4 or MR-RB6K-4.
Cooling with a cooling fan enhances regenerative power. The G3 and the G4 terminals are thermal
sensors. Abnormal overheating of the regenerative option causes the contact between G3 and G4 to
open.
Note. Specifications for contacts between G3 and G4
Maximum voltage: 120 V AC/DC
Maximum current: 0.5 A/4.8 V DC
Maximum capacity: 2.4 VA
