Part 2: Review on Replacement of MR-J3-_A_ with MR-J4-_A_
1. SUMMARY
This section describes the changes to be made when a system using MR-J3-_A_ is replaced with a system
using MR-J4-_A_.
2. CASE STUDY ON REPLACEMENT OF MR-J3-_A_
2.1 Review on Replacement Method
POINT
An HG motor cannot be driven by MR-J3-_A_. When a servo motor is replaced
with an HG motor, servo amplifier also needs to be replaced with MR-J4-_A_
simultaneously.
2.2 Replacement Method
(1) Simultaneous replacement with MR-J4-_A_ 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 6:
Common Reference Material".)
Note Separate repair means replacement.

Simultaneous
replacement?
(1) Simultaneous replacement with MR-J4-_A_ 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).)
