Main circuit power supply
Note 1. For power supply specifications, refer to section 1.3.
2. Between P3 and P4 is connected by default. When using the power factor improving DC reactor, remove the short bar
between P3 and P4. Refer to section 11.11 for details. Additionally, a power factor improving DC reactor and power factor
improving AC reactor cannot be used simultaneously.
3. Connect P/+ and N/- terminals of the brake unit to a correct destination. Incorrect connection destination results in servo
amplifier and brake unit malfunction.
4. Contact rating: 1a contact, 110 V AC, 5 A/220 V AC, 3 A
Normal condition: TH1-TH2 is not conducting. Abnormal condition: TH1-TH2 is conducting.
5. Contact rating: 230 V AC, 0.3 A/30 V DC, 0.3 A
Normal condition: B-C is conducting./A-C is not conducting. Abnormal condition: B-C is not conducting./A-C is conducting.
6. Do not connect more than one cable to each P+ to N- terminals of the servo amplifier.

8. 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, slow the time to turn
off the magnetic contactor.
9. Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the servo
amplifier.
10. When wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded-case circuit breaker.
11. The illustration of the 24 V DC power supply is divided between input signal and output signal for convenience. However, they
can be configured by one.
