12.11 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/CSA Standard, use the wires shown in appendix 10 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
(1) Wires for power supply wiring
POINT
Always use the 600V grade heat-resistant polyvinyl chloride insulated wire (HIV
wire) when using the HF-JP series servo motor.
The following diagram shows the wires used for wiring. Use the wires given in this section or equivalent.
