2.1 MR-J3 series => MR-J4 series Comparison Table of Servo Amplifier Dimensions/Installation Differences

2.1.1 General-Purpose Interface/SSCNET Interface 200 V/100 V class (22 kW or less)

(1) Comparison of Dimensions
The following table shows comparison of the MR-J3 series and MR-J4 series dimensions. Dimensions of
servo amplifiers of 3.5 kW or less, 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 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.
