MR-J4-11KGF-PX to MR-J4-22KGF-PX, MR-J4-11KGF-RZ to MR-J4-22KGF-RZ, MR-J4-
11KGF4-PX to MR-J4-22KGF4-PX, and MR-J4-11KGF4-RZ to MR-J4-22KGF4-RZ (when
using the regenerative option)
The MR-J4-11KGF-PX to MR-J4-22KGF-PX, MR-J4-11KGF-RZ to MR-J4-22KGF-RZ, MR-J4-11KGF4-PX to MR-J4-
22KGF4-PX, and MR-J4-11KGF4-RZ to MR-J4-22KGF4-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.
