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
1) 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.)
2) When the power factor improving DC reactor is not used, between P3 and P4 should be
connected.

Servo amplifier
(Note)
Note. The 100 V class servo amplifiers do not have P3 and P4.
(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 servo motor power
terminals (U/V/W). Otherwise, the servo amplifier and servo motor will malfunction.
