Note 1. For the power suppl

specifications, refer to section 1.3.

2. This dia

ram shows sink I/O interface. For source I/O interface, refer to section 3.8.3.

3. 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). Depending on the main circuit voltage and operation pattern, bus

voltage decreases, and that may cause the forced stop deceleration to shift to the dynamic brake deceleration. When dynamic

brake deceleration is not required, dela

the time to turn off the ma

netic contactor.

4. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo

amplifier.

5. When not usin

the STO function, attach the short-circuit connector came with a servo amplifier.

6. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they

can be confi

ured b

one.

7. Drivin

the on switch and off switch with the DC power suppl

meets IEC/EN 60204-1 requirements.

8. Do not use the 24 V DC interface power supply for the magnetic contactor DC power supply. Always use the power supply

desi

ned exclusivel

for the ma

netic contactor.

9. If ALM (Malfunction) output is disabled with the parameter, configure the power supply circuit which switches off the magnetic

contactor after detection of alarm occurrence on the servo s

stem controlle

side.

10. When wires used for L11 and L21 are thinner than wires used for L1

L3 and N-, use a fuse.

App. 15.2 Power supply capacity

The power supply capacity is the same as that for the AC power supply input. Refer to section 10.2 for

details.

App. 15.3 Selection example of wires

POINT

Selection conditions of wire size are as follows.

Construction condition: Single wire set in midair

Wiring length: 30 m or shorter

The following diagram shows the wires used for wiring. Use the wires given in this section or equivalent.

(1) Example of selecting the wire sizes

Use the 600 V grade heat-resistant polyvinyl chloride insulated wire (HIV wire) for wiring. The following

shows the wire size selection example.

App. 15.4 Molded-case circuit breakers, fuses, magnetic contactors

(1) For main circuit power supply

CAUTION

To prevent the servo amplifier from smoke and a fire, select a molded-case circuit

breaker which shuts off with high speed.

Always use one molded-case circuit breaker and one magnetic contactor with one

servo amplifier.

When using a fuse instead of the molded-case circuit breaker, use the one having the specifications

given in this section.

Note. Use the 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).

(2) For control circuit power supply

When the wiring for the control circuit power supply (L11/L21) is thinner than that for the main circuit

power supply (L1/L2/L3/N-), install an overcurrent protection device (fuse, etc.) to protect the branch

circuit.
