Case Study On Replacement Of Mr-J3-_B; Review On Replacement Method - Mitsubishi Electric MELSERVO-J4 Series Transition Handbook

Part 3: Review on Replacement of MR-J3-_B_ with MR-J4-_B_
Part 3: Review on Replacement of MR-J3-_B_ with MR-J4-_B_
1. SUMMARY
This document describes the changes that are applied to when replacing a system using the MR-J3-_B_ with
a system using the MR-J4-_B_.

2. CASE STUDY ON REPLACEMENT OF MR-J3-_B_

2.1 Review on Replacement Method

MR-J3-_B_
HF-_P/HC-_P/HA-_P
motor
(J3 motor)
(1) Simultaneous replacement with
SSCNET III/H servo system
controller + MR-J4_B_ + J4 series
servo motor (Note 1, 2)
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. When designing a new system, apply simultaneous replacement at (1).
3. Replacing the system allows some J3 series servo motors to drive in MR-J4-_B_ (J4 mode) and MR-J4-_B_ (J3
compatibility mode). Check "Part 7: Common Reference Material" for target motors.

(3) Gradual replacement of
MR-J3-_B_ with MR-J4-_B_
and eventual replacement with
SSCNET III/H servo system

3 - 2
NO
Only the amplifier

and the motor are
replaced.
Replace the servo

servo motor
individually.
