4.1 Review on Replacement Method

MR-J2M-_B
HC-_FS
motor
(1) Simultaneous
replacement with a QDS
motion controller+ MR-
J4-_B_ or a stand-alone
motion controller + MR-
J4-_B_
For details about (3), refer to "[Appendix 1] Summary of MR-J4-_B_-RJ020 + MR-J4-T20".
POINT
Before replacement, note that the dimensions, peripheral circuits, and optional
peripheral devices for the MR-J2M servo amplifier are different from those for
the MR-J4 servo amplifier.
"QDS motion controller" refers to the following model.
Q172DSCPU/Q173DSCPU
"Stand-alone motion controller" refers to the following model.
Q170MSCPU(-S1)
A171SHCPUN
A172SHCPUN
A173UHCPU
A273UHCPU
Q172CPUN
Q173CPUN
QD75M_
A1SD75M_
(QnHCPU + Q3_B)
YES
(2) The QDS motion
