Note 1. For power supply specifications, refer to section 1.2.
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.
3. Connect the P/ and N/
brake unit malfunction.
4. Contact rating: 1b contact, 110VAC_5A/220VAC_3A
Normal condition: TH1-TH2 is conducting. Abnormal condition: TH1-TH2 is not conducting.
5. 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.
6. For the servo amplifier of 3.5kW, always disconnect the wiring between P and D terminals.
7. Do not connect more than one cable to each P to N terminals of the servo amplifier.
8. Always connect between BUE and SD terminals (Factory-wired).
9. In the device setting, assign the forced stop (EMG) to any pin (Refer to section 6.6).
POINT
Connecting PR terminal of the brake unit to P terminal of the servo
amplifier results in brake unit malfunction. Always connect the PR
terminal of the brake unit to the PR terminal of the resistor unit.
