22KB4-PX/MR-J4-11KB4-RZ to MR-J4-22KB4-RZ (when using the regenerative option)
The MR-J4-11KB-PX to MR-J4-22KB-PX, MR-J4-11KB-RZ to MR-J4-22KB-RZ, MR-J4-11KB4-PX to
MR-J4-22KB4-PX, and MR-J4-11KB4-RZ to MR-J4-22KB4-RZ servo amplifiers are not supplied with
regenerative resistors. When using any of these servo amplifiers, always use the regenerative option
MR-RB5R, MR-RB9F, MR-RB9T, MR-RB5K-4, and MR-RB6K-4.
Cooling the regenerative option with cooling fans improves regenerative capability. G3 and G4 are
thermal sensor's terminals. Between G3 and G4 is opened when the regenerative option overheats
abnormally.
Regenerative option
Configure up a circuit which shuts off main
circuit power when thermal protector operates.
