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

2. Always connect P1 - P( ) terminals (Factory-wired). When using the power factor improving DC reactor, refer to section 11.13.

3. Connect the P/ and N/ terminals of the brake unit to a correct destination. Wrong connection results in servo amplifier and

brake unit malfunction.

4. For the servo amplifier of 400V class, a step-down transformer is required.

5. Contact rating: 1a contact, 110VAC_5A/220VAC_3A

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

6. Contact rating: 230VAC_0.3A/30VDC_0.3A

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 and N terminals of the servo amplifier.

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

9. For the servo amplifier of 22kW, do not connect a supplied regenerative resistor to the P and C terminals.
