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 13.2) used to wire the
servo amplifier. For connection with the terminal block TE2 of the MR-J2S-100A or less, refer to
Section 3.11.
The servo motor side connection method depends on the type and capacity of the servo motor. Refer to
Section 3.8.
To comply with the UL/C-UL (CSA) Standard, use UL-recognized copper wires rated at 60 (140 ) or
more for wiring.
