1. OVERVIEW OF MIGRATION FROM Q17nCPUN(-T) TO RnMTCPU

1.1 Benefits of Migration

Migrating from the existing system using Q173CPUN(-T)/Q172CPUN(-T) Motion controllers to a
new system using MELSEC iQ-R series Motion controllers R32MTCPU/R16MTCPU (hereinafter
called RnMTCPU), which support the programs on the Q173CPUN(-T)/Q172CPUN(-T), is
recommended. We also recommend migrating servo amplifiers to the MR-J4 series at the same
time.
Migrating not only allows the system to run for longer periods, but also has the following
advantages.
(1) High-speed operation and high functionality of the Motion controller
The Motion controller RnMTCPU achieves the maximum operation cycle of 0.222 ms/2 axes,
enabling a dramatically fast operation.
The controller also achieves further advanced motion control with a wide variety of motion
control functions.
→ Increased productivity from higher speeds and functionality of the Motion controller.
(2) High-speed communication by SSCNETIII/H
Speeding up and improving noise tolerance of servo network communications are achieved
by optical communication. A long distance cable of 100 m can be also used.
→ Increased speeds over the entire facility
(3) Servo amplifier MR-J4 and servo motor
The latest MR-J4 series achieves high performance operation with a variety of functions
including one-touch tuning, a 22-bit high resolution encoder (4194304 pulse/rev), and 2.5 kHz
speed frequency response. The product lineup includes multi-axis servo amplifiers that
contribute to energy saving, space saving, and reduced wiring of a machine. The MR-J4
series compatible rotary servo motor, HG series enables to output high torque at high speed.
Linear servo motors and direct drive motors are also available. Select the motor type
according to your application from our extensive product lineup.
→ Increase of applications, improved performance, energy saving, downsizing, and reduced
(4) Lower maintenance cost
After 5 years of usage, the products will need maintenance, such as replacement of the whole
circuit board due to the life of components including electrolytic capacitors and memories.
To use the system the longest possible, an early migration to the latest model is
recommended in terms of performance and quality.
→ Increased equipment longevity
wiring of drive systems.
