Note. When using the regenerative 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 max. If the wiring distance is over 30m, 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
(140 ) or
more for wiring.
