4.1.2 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 should
satisfy the defined specifications. (Refer to section 1.3.)
(b) Connection of servo amplifier and servo motor
1) The CNP3A, CNP3B, or CNP3C connector should be connected to each A-axis, B-axis, or C-axis
servo motor. The servo amplifier power output (U/V/W) should match in phase with the servo
motor power input terminals (U/V/W).
