Wires for power supply wiring
POINT
Use 600 V Grade heat-resistant polyvinyl chloride insulated wires (HIV wires) for
HF-JP series servo motor.
The following diagram shows the wires used for wiring. Use the wires given in this section or equivalent.
In this case, the power supply wire used is a 600 V plastic one and the wiring distance is 30 m or less.
When the wiring distance exceeds 30 m, select another wire size in consideration of the voltage drop.
The alphabet letters (a/b/c) on the table correspond to crimp terminals used when wiring a servo
amplifier.
The method of wiring a servo motor differs depending on the type and capacity of the servo motor.
To comply with the UL/cUL (CSA) standard, use UL-approved copper wires rated at 60
˚ C or higher for
wiring.
