Combination Of Converter Unit, Drive Unit, And Servo Motor - Mitsubishi Electric MELSERVO-J2S Series Transition Handbook

Part 5: Review on Replacement of MR-J2S-30 kW or Higher Capacity Models with MR-J4-DU_

1.2 Combination of Converter Unit, Drive Unit, and Servo Motor

(1) MR-J2S series
(a) 200 V class
Converter unit
MR-HP30KA
Note. Make sure that the power running effective torque is 75% or less of 37 kW. Use a DC reactor (MR-DCL37K).
(b) 400 V class
Converter unit
MR-HP55KA4
(2) MR-J4 series
(a) 200 V class
Converter unit
MR-CR55K
(b) 400 V class
Converter unit
MR-CR55K4
POINT
MR-J2S-_A_/B_ cannot drive an HG motor. When the servo motor is replaced
with an HG motor, simultaneous replacement with MR-J4-_A_/B_ and an HG
motor is necessary.
If the existing system is any of the combinations in the following table, it is
recommended to replace both the servo amplifier and servo motor with an
MRJ4-_A_ and HG motor at the same time. When an HG motor is adopted, the
capacity of the servo amplifier needs to be changed. (Consider replacement,
referring to "torque characteristics" described in "Part 8: Review on Replacement
of Motor".)
