(1) Comparison of Dimensions
The following table shows comparison of the MR-J3 series and MR-J4 series dimensions.The two are
the same in height, width, mounting screw pitch, and screw size, and therefore compatible in mounting.
When the servo amplifier is mounted so that the heat sink is inside the cabinet, the depth vary.
