14.2 Auxiliary equipment

Always use the devices indicated in this section or equivalent. To comply with the EN Standard or UL/C-
UL (CS4) Standard, use the products which conform to the corresponding standard.

14.2.1 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
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.
The alphabets (a, b, c) in the table correspond to the crimping terminals (Table 14.2) used to wire the
servo amplifier. For connection with the terminal block TE2 of the MR-J2-100C or less, refer to Section
3.7.
The servo motor side connection method depends on the type and capacity of the servo motor. Refer to
Section 3.3.
To comply with the UL/C-UL (CS4) Standard, use UL-recognized copper wires rated at 60 (140) or
more for wiring.
