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.
-When inverter-driving a 400V class 3-phase motor or a 400V class high-efficiency, 3-phase motor, measures must be taken with
motor insulation.
-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.
-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.
