16.4.2 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 (L
the defined specifications. (Refer to section 1.2.)
(b) Connection of servo amplifier and servo motor
1) The servo motor power supply terminals (U, V, W) of the servo amplifier match in phase with the
power input terminals (U, V, W) of the servo motor.
2) The power supplied to the servo amplifier should not be connected to the servo motor power supply
terminals (U, V, W). To do so will fail the connected servo amplifier and servo motor.
3) The earth terminal of the servo motor is connected to the PE terminal of the servo amplifier.
4) P -P (For 11kW or more, P
