Note 1. For power supply specifications, refer to section 1.3.

2. For the servo amplifier of 7 kW, always disconnect the lead wire of built-in regenerative resistor, which is connected to the P+

and C terminals.

3. Always connect between P3 and P4 terminals. (factory-wired) Use either the power factor improving DC reactor or the power

factor improving AC reactor. When using the power factor improving DC reactor, refer to section 11.11.

4. Connect P/+ and N/- terminals of the brake unit to a correct destination. Incorrect connection results in servo amplifier and

brake unit malfunction.

5. Contact rating: 1b contact, 110 V AC_5 A/220 V AC_3 A

Normal condition: TH1-TH2 is conducting. Abnormal condition: TH1-TH2 is not conducting.

6. 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.

7. Do not connect more than one cable to each P+ to N- terminals of the servo amplifier.

8. Always connect BUE and SD terminals. (factory-wired)

9. Connect MSG and SD terminals of the brake unit to a correct destination. Incorrect connection results in servo amplifier and

brake unit malfunction.

10. For the cable to connect the terminal block and the P+ and N- terminals of the servo amplifier, use the cable indicated in (3)(b)

of this section.

11. 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.

12. Turn off EM2 when the main power circuit power supply is off.

13. When wires used for L11 and L21 are thinner than wires used for L1, L2, and L3, use a molded case circuit breaker.
