*1 For the power supply specifications, refer to "Servo amplifier standard specifications" in the following user's manuals.

*2 Use a magnetic contactor with an operation delay time (interval between current being applied to the coil until closure of contacts) of 80
ms or less (160 ms or less for 5 kW or more). Bus voltage may drop depending on the main circuit voltage and operation pattern,
causing a dynamic brake deceleration during a forced stop deceleration. If dynamic brake deceleration is not required, delay the time to
turn off the magnetic contactor.
*3 Operating the on switch and off switch with the DC power supply meets IEC/EN 60204-1 requirements.
*4 Do not share the 24 V DC power supply for interface with a magnetic contactor. Always use the power supply designed exclusively for
the magnetic contactor.
*5 If wires used for L11 and L21 are thinner than wires used for L1, L2, L3, and N-, use a fuse.

Selection example of wires
Selection conditions of wire size are as follows.
Construction condition: Single wire set in midair
Wiring length: 30 m or shorter
The following shows the wires used for wiring. Use the wires given in this section or equivalent wires.
■Example of selecting the wire sizes
Use 600 V Grade heat-resistant polyvinyl chloride insulated wires (HIV wires) for wiring. The following shows the wire size
selection example.
