4. CONNECTION OF SERVO AMPLIFIER AND SERVO MOTOR

4.3 Selection example of wires

The following diagram shows the wires used for wiring. Use the wires given in this section or equivalent.
When using the 600 V Grade heat-resistant polyvinyl chloride insulated wire (HIV wire)
Wire size selection examples for HIV wires are indicated below.
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
600 V 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 4 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: 30 m or less
