Note 1 Terminals 13, 14 are N/O contact outputs. When the dynamic brake has stuck, terminals 13, 14 are opened. Therefore, configure
up the circuit to prevent servo-on in the external sequence.
2. For converter unit and servo amplifier 400 V class, stepdown transformer is required for coil voltage of magnetic contactor more
than 200 V class.
3. Assign the dynamic brake interlock (DB) in parameter No.PD07 to PD09.
4. Refer to section 13.1.3 for the power supply specifications.
5. Make up a sequence that turns off the drive unit forced stop (EM1) and the converter unit forced stop (EM1) at the same time.

13.9.4 Selection example of wires
POINT
Wires indicated in this section are separated wires. When using a cable for
power line (U, V, and W) between the servo amplifier and servo motor, use a
600V grade EP rubber insulated chloroprene sheath cab-tire cable (2PNCT).
For selection of cables, refer to appendix 6.
To comply with the UL/C-UL (CSA) Standard, use UL-recognized copper
wires rated at 60
(140 ) or more for wiring. To comply with other
standards, use a wire that is complied with each standard
Selection condition of wire size is as follows.
Construction condition: One wire is constructed in the air
Wire length: 30m or less
The following diagram shows the wires used for wiring. Use the wires given in this paragraph or equivalent.
