18.4.3 Wiring check
(1) Power supply system wiring
Before switching on the main circuit and control circuit power supplies, check the following items.
(a) Power supply system wiring
The power supplied to the power input terminals (24/0/PM) of the servo amplifier should satisfy the
defined specifications. (Refer to section 18.1.3.)
(b) Connection of servo amplifier and servo motor
1) The servo amplifier power output (U/V/W) should match in phase with the servo motor power
input terminals (U/V/W).

2) The power supplied to the servo amplifier should not be connected to the power outputs (U/V/W).
Otherwise, the servo amplifier and servo motor will fail.

4) The CN2 connector of the servo amplifier should be connected to the encoder of the servo motor
securely using the encoder cable.
(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 CN1 connector. You can use this function
to check the wiring. In this case, switch on the control circuit power supply only.
For details of I/O signal connection, refer to section 18.3.5.
(b) A voltage exceeding 24 V DC is not applied to the pins of the CN1 connector.
(c) Between plate and DOCOM of the CN1 connector should not be shorted.
