Part 4: Review on Replacement of MR-J2S-_CP_/CL_ with MR-J4-_A_-RJ
1. SUMMARY
This section describes the changes to be made when a system using MR-J2S-_CP_/CL_ is replaced with a
system using MR-J4-_A_-RJ.

2. CASE STUDY ON REPLACEMENT OF MR-J2S-_CP_/CL_

2.1 Consideration of Replacement Method

(1) Simultaneous replacement with MR-J4-_A_-RJ and
an HG motor
Although heavier burdens including a longer
construction period need to be borne, once replaced
the system can be operated for a long period of time.
(Refer to Section 2.2 (1).)
Note 1. Separate repair means replacement.
2. No "renewal tool" is available for MR-J2S-_CL_.

2.2 Replacement Method

(1) Simultaneous replacement with MR-J4-_A_RJ and an HG motor
The currently used connectors or cables need to be replaced. The parameters of the existing system can
be transferred with the parameter converter function of MR Configurator2. (Refer to "Part 7: Common
Reference Material".)
[Existing system]
POINT
MR-J2S-_CP_/CL_ cannot drive an HG motor. When a servo motor is replaced
with an HG motor, servo amplifier also needs to be replaced with MR-J4-_A_-RJ
+ HG simultaneously.
