17.4.2 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 (L1, L2, L3, L11, L21) of the servo amplifier must satisfy
the defined specifications. (Refer to section 1.2.)
(b) Connection of servo amplifier and servo motor
1) The servo motor power outputs (U, V, and W) of the servo amplifier must match in phase with the
power input terminals (U, V, and W) of the servo motor.
