Case Study On Replacement Of Mr-J3W-_B; Review On Replacement Method; Servo Amplifier Replacement Model - Mitsubishi Electric MELSERVO-J3 Series Handbook

Part 4: Replacement of MR-J3W-_B with MR-J4W2-_B
Part 4: Replacement of MR-J3W-_B with MR-J4W2-_B
1. SUMMARY
This section describes the changes to be made when a system using MR-J3W-_B is replaced with a system
using MR-J4W2-_B.

2. CASE STUDY ON REPLACEMENT OF MR-J3W-_B

2.1 Review on Replacement Method

J3 series servo motor
HF-_P motor
HC-_P motor
(1) Replace with SSCNETIII/H
servo system controller +
MR-J4W2-_B + J4 series
servo motor simultaneously.
(Note 1)
Note 1. 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.
2. Replacing the system, you can drive some J3 series servo motors with MR-J4W2-_B (J4 mode) and MR-J4W2-_B (J3
compatibility mode). Refer to "Part 6 Common Reference Material" for the applicable motor.

2.2 Servo Amplifier Replacement Model

The following shows the target models (MR-J3W series) and replacement models (MR-J4W2-_B servo
amplifier).
