For installation of an external brake resistor to the servo amplifiers MR-J2S-500B and MR-J2S-
700B and MR-J2S-350B4 to MR-J2S-700B4 always remove the built-in regenerative brake
resistor. To do this loosen the cables attached to terminals P and C. Then fasten the cables to
the housing of the servo amplifier using the accessory screw (refer fig. 7-5).
