Part 2: Review on Replacement of MR-J3-_A_ with MR-J4-_A_

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_

HF-_P/HC-_P/HA-_P

(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).)

Note. Separate repair means replacement.

(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 7:

Common Reference Material".)

[Existing system]

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.
