Part 5: Review on Replacement of MR-J3-DU_ with MR-J4-DU_

2.2 Combination of converter unit, drive unit, and servo motor

(1) MR-J3 series
(a) 200 V class
Converter unit
MR-J3-CR55K
(b) 400 V class
Converter unit
MR-J3-CR55K4
POINT
MR-J3-_A_/MR-J3-_B_ cannot drive an HG motor. When the servo motor is
replaced with an HG motor, simultaneous replacement withMR-J4-_A_/MR-J4-
_B_ and an HG motor is necessary.
When an "HA-LP motor " shown below is used, simultaneous replacement with
"MR-J4-_A_/MR-J4-_B_ + HG motor is recommended. When an HG motor is
adopted, the capacity of the servo amplifier needs to be changed. (Consider
replacement, referring to "2.7 Comparison of Servo Motor Torque
Characteristics" described in "Part 7: Review on Replacement of Motor".)
