11.11 Selection example of wires
POINT
Refer to section 11.1.5 for SSCNET cable.
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

Note 1. Alphabets in the table indicate crimping tools. For crimping terminals and applicable tools, refer to (1) (c) in this section.
2. When connecting to the terminal block, be sure to use the screws which are provided with the terminal block.
3. For the servo motor with a cooling fan.
4. Wires are selected based on the highest rated current among combining servo motors.
Use wires 8) of the following sizes with the power regeneration converter (FR-RC-(H)).
