Customer to prepare.
- This diagram shows cases for motors with standard Japanese domestic specications. Please consult with us for motors with
overseas specications.
- For brake types, see Table 1-6 on P7.
- When inverter-driving a 400V class 3-phase motor or a 400V class high-eciency, 3-phase motor, measures must be taken with
motor insulation.
- Brake action delay time is dierent for normal and quick braking circuits.
Table 7-2 on P35 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 P32.
- 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.
