3. BASIC CONFIGURATION
[Before replacement]
MR-J2S series
• Servo amplifier
• Servo motor
Note. MR-J4 series servo amplifier and servo motor are required to be purchased separately.
3.1 Important Points to Note When Replacing
(1) Please note that replacement may not be possible when multiple units are set in a line due to the
clearance between the servo amplifiers, the model, and the number of units. (Refer to Chapter 8 of this
Appendix regarding the dimensions)
(2) Depending on the condition of the existing setup, sometimes noise reduction techniques are necessary
when replacing.
(3) When using the existing cables, please consider the remaining life of the cables. If deterioration is
significant, replacing with a new cable is recommended.
(4) Because the conversion cable does not have a long bending life, fix the cable when using.
(5) Contact us if using an encoder cable longer than 50 m with long distance wiring. (For secondary and
simultaneous replacement) Contact us when replacing with an HG-KR or MR motor if the existing
encoder cable is longer than 30 m.
(6) No oil seal is attached to the standard type MR-J4 servo motor. Take care when selecting if the existing
MR-J2S servo motor has an attached oil seal. Contact a sales representative if a servo motor with an oil
seal is required.
(7) Depending on machine conditions (inertia, load, etc.), there is a possibility of insufficient servo amplifier
capacity after replacement. Carefully consider the capacity in relation to the replacement.
(8) Although use of dynamic brake resistance standardly equipped to the replacement MR-J4 servo
amplifier is possible, take care because the coasting distance differs depending on the characteristics of
the dynamic brake. In addition, do not use dynamic braking at high frequencies.
(9) Check Part 9 of this document for important points to note when using optional or peripheral equipment.
(10) Contact a sales representative if the existing MR-J2S servo amplifier or servo motor is a special
product.
(11) Although the servo motor model of the MR-J2S-series servo motor may not be displayed properly with
MR Configurator2, this is normal. Do not use the MR Configurator2 advanced functions (machine
analyzer, gain search, machine simulation, etc.) because they do not work accurately.
