(1) Comparison of dimensions
The following table shows comparison of the MR-J3 series and MR-J4 series dimensions. Dimensions of
servo amplifiers of 2 kW or less, 5 kW, 7 kW, and 22 kW are the same and have compatibility in
mounting. Note that the width and horizontal mounting screw pitch have been changed for servo
amplifiers of 3.5 kW. For servo amplifiers of 11 kW and 15 kW, note that the width, vertical/horizontal
mounting screw pitch, and screw size have been changed.
