Customer needs to prepare.
- This diagram shows cases for motors with standard Japanese domestic specifications. Please consult with us for motors with overseas
specifications.
- For brake types, see Table 1-1 on P5.
- Brake action delay time is different between normal and quick braking circuits.
Table 7-2 on P39 shows action delay time. Choose the circuit that matches work requirements.
- Use a quick braking circuit to improve hoisting equipment and stopping precision.
- Use a quick braking circuit When a phase-advancing capacitor is mounted.
- For information on electromagnetic contactors and varistors for quick braking circuits, see Table 6-4 on P37.
- Use with a quick braking circuit for FB-20 or FB-30.
- FB-20, 30 are shipped with a short circuit plate connecting terminals 5 and 6. Remove the short circuit plate when wiring.
- Always use the inverter’s power source side for the brake power source.
- Match the opening and closing of the brake circuit’s electromagnetic contactor to the timing of the inverter control.
