When using serial linear encoder with MR-J4-_GF_-RJ
The configuration diagram is an example of MR-J4-20GF-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 the following
depending on servo amplifiers you use.

*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-J4-200GF-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 the following.

*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 the following.

*6 Connect the thermistor to THM of the branch cable and connect the encoder cable to SCALE correctly. Incorrect connection triggers [AL.
