Replacement Method - Mitsubishi Electric MELSERVO-J2S Series Transition Handbook

Part 3: Review on Replacement of MR-J2S-_B_ with MR-J4-_B_

2.2 Replacement Method

This section shows replacements using a QDS motion controller and an SSCNETIII/H-compatible stand-
alone motion controller as examples.
For replacements using modules other than the above, refer to the following manuals.
Transition from A17nSHCPUN/A173UHCPU Series to Q Series Handbook
(1) For simultaneous replacement
QDS motion controller + MR-J4-_B_ + HG motor
QnUD(E)(H)CPU + QDS motion controller + Q3_DB
High-speed motion control and excellent extensibility can reduce
cycle time.
"QDS motion controller" refers to the following model.
・Q172DSCPU
・Q173DSCPU
(2) For replacement of a controller and a servo amplifier
QDS motion controller + MR-J4-_B_ + HC-_FS/HA-_FS motor
QnUD(E)(H)CPU + QDS motion controller + Q3_DB
MR-J4-_B_
HC-_FS/HA-_FS
motor
Although the HC/HA motor can continue to be used without any changes made (Note 1 and 2), the encoder
resolution of the servo motor will be 17 bits.
Note 1. Consider simultaneous replacement of devices when designing a new system.
2. Please contact your local sales office for the target servo motor and servo amplifier.
SSCNET III/H-compatible stand-alone motion controller:
MR-J4-_B_
HG motor
High performance equivalent to that of a QDS motion controller
can be achieved at a lower cost.
"Stand-alone motion controller" refers to the following model.
・Q170MSCPU(-S1)
Stand-alone motion controller + MR-J4-_B_+ HC-_FS/HA-_FS motor
SSCNET III/H-compatible stand-alone motion controller:
3 - 4
Stand-alone motion controller + MR-J4-_B_ + HG motor
Q170MSCPU (-S1)
Q170MSCPU(-S1)
MR-J4-_B_
HC-_FS/HA-_FS
motor
MR-J4-_B_
HG motor
