POINT
Refer to section 11.1.5 for SSCNET cable.
Wires indicated in this section are separated wires. When using a cab le for
power line (U, V, and W) between the servo amplifier and servo m otor, use a
600V grade EP rubber insulated chloroprene sheath cab-tire cable (2P NCT).
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
