15.4.3 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, and PM) of the servo amplifier should satisfy the
defined specifications. (Refer to section 1.3.)
(b) Connection of servo amplifier and servo motor
1) The servo motor power terminals (U, V, and W) should match in phase with the servo motor power
input terminals (U, V, and W).

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.
(b) 24VDC or higher voltage is not applied to the pins of the CN3 connector.
(c) SD and DOCOM of the CN3 connector is not shorted.
