4. STARTUP
4 - 4
(c) When you use an option and auxiliary equipment
When you use a regenerative option
The regenerative option wire should be connected between P+ terminal and C terminal.
A twisted cable should be used. (Refer to section 11.2.4.)
(2) I/O signal wiring
(a) The I/O signals should be connected correctly.
Use DO forced output to forcibly turn on/off the pins of the CN3 connector. This function can be used
to perform a wiring check. In this case, switch on the control circuit power supply only.
Refer to section 3.2 for details of I/O signal connection.
(b) 24 V DC or higher voltage is not applied to the pins of the CN3 connector.
(c) Plate and DOCOM of the CN3 connector is not shorted.

4.1.3 Surrounding environment
(1) Cable routing
(a) The wiring cables should not be stressed.
(b) The encoder cable should not be used in excess of its bending life. (Refer to section 10.4.)
(c) The connector of the servo motor should not be stressed.
(2) Environment
Signal cables and power cables are not shorted by wire offcuts, metallic dust or the like.
4.2 Startup
POINT
The controller recognizes MR-J4 2-axis servo amplifiers as two servo amplifiers
and 3-axis servo amplifiers as three servo amplifiers. For this reason, select
"MR-J4-B" for each of the A-axis, the B-axis, and the C-axis. The following table
shows the servo amplifier settings in the controller when the MR-J4 multi-axis
servo amplifier is used.

Motion controller
(R_MTCPU/Q17_DSCPU) Select "MR-J4-B" in the system setting screen.
Simple motion module
(RD77MS_/QD77MS_) Select "MR-J4-B" in "Servo series" [Pr. 100] of the servo
parameter.
Connect the servo motor with a machine after confirming that the servo motor operates properly alone.
