14. USING A LINEAR SERVO MOTOR
14.1.2 Servo system with auxiliary equipment
CAUTION
(1) MR-J4-_B_
The following configuration diagram shows an example for using a linear servo motor with MR-J4-10B.

Note 1. The power factor improving AC reactor can also be used. In this case, the power factor improving DC reactor cannot be used.
When not using the power factor improving DC reactor, short P3 and P4.
2. A 1-phase 200 V AC to 240 V AC power supply may be used with the servo amplifier of MR-J4-70B(-RJ) or less. For 1-phase
200 V AC to 240 V AC, connect the power supply to L1 and L3. Leave L2 open. For power supply specifications, refer to
section 1.3.
3. Depending on the main circuit voltage and operation pattern, bus voltage decreases, and that may cause the forced stop
deceleration to shift to the dynamic brake deceleration. When dynamic brake deceleration is not required, slow the time to turn
off the magnetic contactor.
4. For the branch cable, use the MR-J4THCBL03M (optional).
5. Always connect between P+ and D terminals. When using the regenerative option, refer to section 11.2.
6. Connect the thermistor to THM of branch cable and connect the encoder cable to SCALE correctly. Incorrect setting will trigger
[AL. 16].
Connecting a linear servo motor for different axis to the U, V, W, or CN2 may
cause a malfunction.
POINT
Equipment other than the servo amplifier and linear servo motor are optional or
recommended products.
When using the linear servo motor, set [Pr. PA01] to "_ _ 4 _".
