2.1 MR-J2S ⇒ MR-J4 Comparison Table of Servo Amplifier Dimensions/Installation Differences

2.1.1 General-purpose interface/SSCNET interface 200 V class (22 kW or less)

The following table shows comparison of the MR-J2S series and MR-J4 series dimensions. The height and
width of the MR-J4 series are the same or smaller than the MR-J2S series basically. The depth is larger for
the 400 W and 600 W capacities. The replacements for 1 kW or less capacity types are possible using the
same mounting holes. The number of mounting screws is different for the 2 kW and 3.5 kW capacities, and
the mounting screw distance is different for the 5 kW to 22 kW capacities. The screw sizes are different for
the 11 kW and 15 kW capacities. (Refer to the comparison of dimensions.)

2.1.2 General-purpose interface/SSCNET interface 100 V class (0.4 kW or less)

The following table shows comparison of the MR-J2S series and MR-J4 series dimensions. The height and
width of the MR-J4 series are the same or smaller than the MR-J2S series basically. The depth is larger for
the 400 W and 600 W capacities. The mounting dimensions are interchangeable.
