Replacemnet MR-J2S to MR-J4

Features MR-J4

• Complete transitions in a short time by using existing wiring and mounting holes.
• This renewal tool allows replacements to be made in stages, such as primary replacement of only the amplifier or secondary replacement up to the motor
• The servo amplifier can be replaced independently, without replacing the host controller or SSCNET cable
• The MR-J2S servo amplifier motor can be controlled with the standard MR-J4 servo amplifier.
•  The encoder conversion cable is available as a single part.

Precautions for Replacement

• MR-J2 Series replacements are not supported. (The encoder conversion cable can be used only for amplifier-motor package replacement.)
• The initialization time after power ON differs for the MR-J2S servo amplifier and MR-J2S servo amplifier so it may be necessary to change the program in existing system. (*Pay special attention to the magnetic brake release time for the vertical axis. The vertical axis could drop)
•  When making a secondary package replacement, the monitor output value (motor rotation speed) will differ from the existing amplifier because of a difference in the motor's maximum rotation speed. The program must be changed when using the monitor output with existing system.
• Note that even when this renewal tool is used, some MR-J2S servo functions may not be 100% compatible.
• The outline dimensions will be larger than the existing MR-J2S servo amplifier when using this renewal tool. Refer to the outline dimensions on the back page for details on the dimensions. Always confirm that there is sufficient space before selecting this tool.
• Depending on the situation, it may be necessary to change the existing wiring or add a noise filter, etc. as a noise countermeasure when using the servo system controller and positioning module (module: A1SD75P, etc.).
• Refer to Guide for Replacing MR-J2S/J2M Series with J4 Series "L (N) 03092" issued by Mitsubishi Electric, and the "Guide for Replacing MELSERVO-J2S Series  using the MR-J2S Renewal Tool (X903120701)" available on the Mitsubishi Electric System & Service web site for replacing the MR-J2S Series with the MR-J4 Series.
