13. OPTIONS AND AUXILIARY EQUIPMENT

13.2 Auxiliary equipment

Always use the devices indicated in this section or equivalent. To comply with the EN Standard or UL/C-
UL (CSA) Standard, use the products which conform to the corresponding standard.

13.2.1 Recommended wires

(1) Wires for power supply wiring
The following diagram shows the wires used for wiring. Use the wires given in this section or
equivalent.
Power supply
Regenerative brake option
Note: When using the regenerative brake option, always remove the wiring across D-P.
The following table lists wire sizes. The wires used assume that they are 600V vinyl wires and the
wiring distance is 30m(98.4ft) max. If the wiring distance is over 30m(98.4ft), choose the wire size in
consideration of voltage drop.
Refer to Section 3.11 for connection with the connector (CNP1, CNP2).
The servo motor side connection method depends on the type and capacity of the servo motor. Refer to
Section 3.8.
To enable the built-in regenerative brake, connect the wiring across D-P. (Refer to Section 3.7.2 for the
connection method.)
To comply with the UL/C-UL (CSA) Standard, use UL-recognized copper wires rated at 60
more for wiring.
