18. MR-J4-03A6 SERVO AMPLIFIER

18.8.3 Selection example of wires

The following diagram shows the wires used for wiring. Use the wires or equivalent given in this section.
24 V DC power supply
48 V DC power supply
The following shows the wire size selection example.

18.8.4 Circuit protector

Control circuit power supply (24 V DC)
Main circuit power supply (48 V DC)
Main circuit power supply (24 V DC)
Note. For operation characteristics, use an intermediate speed type.
POINT
To comply with the IEC/EN/UL/CSA standard, use the wires shown in appendix
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.
