MC: Electromagnetic contactor
OLR: Overload protection device or electronic thermal relay
VR: Varistor (for protecting contact points, rectifier, etc.)
Customer 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 1-6 on P7.
-Brake action delay time is different 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 quick braking circuits, gang the brake circuit’s electromagnetic contactor to the motor’s electromagnetic contactor.
