13.9.4 Selection example of wires
POINT
Wires indicated in this section are separated wires. When using a cable for
power line (U, V, and W) between the servo amplifier and servo motor, use a
600V grade EP rubber insulated chloroprene sheath cab-tire cable (2PNCT).
For selection of cables, refer to appendix 6.
To comply with the UL/C-UL (CSA) Standard, use UL-recognized copper
wires rated at 60
(140 ) or more for wiring. To comply with other
standards, use a wire that is complied with each standard
Selection condition of wire size is as follows.
Construction condition: One wire is constructed in the air
Wire length: 30m or less
The following diagram shows the wires used for wiring. Use the wires given in this paragraph or equivalent.
