Case Study On Migration; Whole System Migration (Recommended) - Mitsubishi Electric Q172DCPU Migration Manual

1. OVERVIEW OF MIGRATION FROM Q17nDCPU(-S1) TO Q17nDSCPU

1.4 Case Study on Migration

The following describes a case study for migrating the existing system using Q17nDCPU(-S1).

(1) Whole system migration (recommended)

The controller, servo amplifiers, servo motors, and servo system network are replaced
simultaneously. Although a large-scale installation is required, the whole system migration
allows the system to operate for longer periods. (Refer to section 1.4.1.)
(2) Phased migration (When the whole system migration is difficult due to the installation
period and cost.)
The controller is replaced with Q17nDSCPU in the first phase, and then the MR-J3-B servo
amplifiers are gradually replaced with MR-J4-B.
(Refer to section 1.4.2.)
(3) Separate repair
This is a replacement method for when the controller, the servo amplifier, or the servo motor
malfunctions. (Refer to section 1.4.3.)
