Part 7: Review on Replacement of Optional Peripheral Equipment
(1) Wires for power supply wiring
The following diagram shows the wires used for wiring. Use the wires given in this section or equivalent.
In this case, the power supply wire used is a 600 V plastic one and the wiring distance is 30 m or less.
When the wiring distance exceeds 30 m, select another wire size in consideration of the voltage drop.
The alphabet letters (a/b/c) on the table correspond to crimp terminals used when wiring a servo
amplifier.
The method of wiring a servo motor differs depending on the type and capacity of the servo motor.
To comply with the UL/cUL (CSA) standard, use UL-approved copper wires rated at 60˚C or higher for
wiring.
