Note 1. For power supply specifications, refer to section 1.3.
2. For the servo amplifier of 5k and 7kW, always disconnect the lead of built-in regenerative resistor, which is connected to the P
and C terminals. For the servo amplifier of 11k and 15kW, do not connect a supplied regenerative resistor to the P and C
terminals.
3. Always connect P
1 and P2 terminals (P1 and P for the servo amplifier of 11k and 15kW) (Factory-wired). When using the power
factor improving DC reactor, refer to section 11.13.
4. Connect the P/
and N/ terminals of the brake unit to a correct destination. Wrong connection results in servo amplifier and
brake unit malfunction.
5. Contact rating: 1b contact, 110VAC_5A/220VAC_3A
Normal condition: TH1-TH2 is conducting. Abnormal condition: TH1-TH2 is not 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. For the servo amplifier of 11kW or more, connect the thermal relay censor of the servo amplifier.
8. Do not connect more than one cable to each P and N terminals of the servo amplifier.
9. Always connect BUE and SD terminals (Factory-wired).
10. Connect the MSG and SD terminals of the brake unit to a correct destination. Wrong connection results in servo amplifier and
brake unit malfunction.
11. For the cable to connect the terminal block and the P and N terminals of the servo amplifier, use the cable indicated in (4) (b) of
this section.

Note 1. For power supply specifications, refer to section 1.3.
2. Always connect P
1 - 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.

(3) Precautions for wiring
The cables between the servo amplifier and the brake unit, and between the resistor unit and the brake unit
should be as short as possible. Always twist the cable longer than 5m (twist five times or more per one
meter). Even when the cable is twisted, the cable should be less than 10m. Using cables longer than 5m
without twisting or twisted cables longer than 10m, may result in the brake unit malfunction.
