15. USING A LINEAR SERVO MOTOR
15 - 4
(2) When using serial linear encoder with MR-J4-_A_-RJ
The configuration diagram is an example of MR-J4-20A-RJ. When using the other servo amplifiers, the
configuration will be the same as rotary servo motors except for connections of linear servo motors and
linear encoders. Refer to section 1.8 depending on servo amplifiers you use.

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-J4-200A-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 the 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].
