[Appendix 1] Summary of MR-J4_B_-RJ020 + MR-J4-T20
1. SUMMARY
This [Appendix 1] describes the "MR-J4-_B_-RJ020" servo amplifier that supports the SSCNET conversion
unit for MR-J2S-_B_ and "MR-J4-T20" SSCNET conversion unit for MR-J2S-_B_.
Ensure to use the MR-J4-T20 with the MR-J4-_B_-RJ020.
Combining MR-J4-_B_-RJ020 with MR-J4-T20 makes it possible to connect MR-J4-_B_-RJ020 with
SSCNET for MR-J2S-_B_
The MR-J4-_B_-RJ020 servo amplifier is equipped with "J2S compatible mode (factory default)" and "J4
mode" as the operation mode. "J2S compatible mode" is the operation mode compatible with the
conventional features of the MR-J2S-B series.
When using in the J4 mode, refer to "[Appendix 1] 12 MODE SWITCHING METHOD".
1.1 Features
1.1.1 Servo amplifier connectable to SSCNET compatible controller
MELSERVO-J4 series servo amplifier connectable to SSCNET connected to MR-J2S-_B_
Using the SSCNET conversion unit for MR-J2S-_B_, the MR-J4-_B_ servo amplifier can be
connected to the SSCNET compatible servo system controller for MR-J2S-_B_.
● The MR-J4-_B_-RJ020 servo amplifier combined with the MR-J4-T20 SSCNET
conversion unit can be connected to the SSCNET compatible servo system controller for
MR-J2S-_B_.
● The MR-J4-compatible HG series servo motor can be driven.
● One SSCNET conversion unit is required per amplifier.
● New features of MR-J4 cannot be used because the amplifier operates in J2S mode.
● The servo amplifier is recognized as MR-J2S by the controller. However, for the
parameter described in the following table, changes to the program or the parameter are
required as necessary.
