Customer to prepare.
- This diagram shows cases for motors with standard Japanese domestic specications. Please consult with us for motors with
overseas specications.
- For brake types, see Table 1-6 on P7.
- Brake action delay time is dierent 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.
- For plugging operations using a quick braking circuit, gang the brake circuit’s electromagnetic contactors to the motor’s normal
and reverse rotation electromagnetic contactors.
