Selection Example Of Wires - Mitsubishi Electric MR-J4W2-0303B6 Instruction Manual

18. MR-J4W2-0303B6 SERVO AMPLIFIER

18.8.3 Selection example of wires

(1) Wires for power supply wiring
The following diagram shows the wires used for wiring. Use the wires or equivalent given in this section.
The following shows the wire size selection example.
POINT
Refer to section 11.1.2 for SSCNET III cable.
To comply with the IEC/EN/UL/CSA standard, use the wires shown in app. 4 for
wiring. To comply with other standards, use a wire that is complied with each
standard.
Selection conditions of wire size are as follows.
Construction condition: Single wire set in midair
Wire length: 30 m or less
The voltage drops because of the cable conductor resistance. Especially for
main circuit/control circuit power supply wiring, wire to secure the required input
voltage at servo amplifier input section. It is recommended that the cable length
be as short as possible.
