1. OVERVIEW OF A-MOTION REPLACEMENT
3. MERITS OF REPLACEMENT
It is recommended to replace A-Motion to the latest iQ Platform Motion CPU Q173DSCPU/Q172DSCPU
(the following QDS-Motion) or Stand-alone Motion CPU Q170MSCPU-S1.
As the merits shown below, it is strongly recommended to use the latest module, QDS-Motion and
MR-J4 amplifier.
When a servo network cannot be replaced and A-Motion is replaced with Q173CPUN/Q172CPUN
(hereafter called QN-Motion), refer to "4. REPLACEMENT FROM A-MOTION TO QN-MOTION". However,
replacing A-Motion with QN-Motion is not recommended since QN-Motion is not the latest model. In
addition, the production of MR-J2S series servo amplifiers and HC series servo motors will stop in August,
2015. If these products need to be continuously used after the production stoppage, changing the system
used to an alternative system will be required. (For details, refer to Section 4.2 to 4.3.)
In order to use a system for a long time with no system modification after the replacement, it is
recommended to replace A-Motion with QDS-Motion or Stand-alone Motion.
3.1 Multiple CPU System (QDS-Motion) with Q Series PLC Module
A system with high flexibility and extensibility can be constructed using various iQ Platform-compatible
modules. An equipment that match the varied request by extensive products can be selected.
-->
Takt time of Production line will be shorten by the equipment capability of expansion and high
performance.
3.2 High-speed and High Performance of Motion CPU
The operation speed of a Motion CPU can be significantly improved: a Motion CPU has an operation
cycle of up to 0.22ms/4 axes (QDS-Motion SV22) or 0.44ms/4 axes (Stand-alone Motion SV22). And as
there are extremely abundant motion control functions, it can support the advanced motion control.
-->
Takt time of Production line will be shorten by the high-speed motion control capability and
high performance.
3.3 High-speed, Noise Free Communication by SSCNET III(/H)
SSCNET III(/H) Servo network communication realizes high-speed response (Communication speed:
150Mbps (simplex)/300Mbps (duplex)) and eliminates the influence of noise by utilizing an optical
communication system.
-->
The influence of noise by wiring can be suppressed, and the operation of equipment will be
stabilized.
3.4 MR-J4 Amplifier + HG Servo Motor (QDS-Motion)
The latest MR-J4 series includes various functions such as one-touch tuning and realizes the high
performance with speed response frequency of 2.5 kHz and encoder resolution of 22 bits (4194304
pulses/rev). The quantity of rare earth metals is reduced for HG series, the servo motor series appropriate
for QDS-Motion.
-->
The influence of noise by wiring can be suppressed, and the operation of equipment will be
stabilized.
3.5 Space Economization (Stand-alone Motion)
A power supply module, a PLC, and a motion controller are integrated without degrading the high
performance of iQ Platform, and this contributes cost reduction and downsizing the equipment. Built the
mark detection and the synchronous encoder I/F in, and it will support the packing machine system without
using special module.
-->
Small-size equipment and cost performance will be compatible.
