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.
- Use with a quick braking circuit. For information on electromagnetic contactors for quick braking circuits, see Table 6-4 on P32.
- Rectiers are external to the main unit. Rectiers are made for indoor use. Install in an area where they will not come into contact
with water, etc.
- The brake unit is for 200V class. For 400V class power sources, prepare a 400V/200V transformer.
- For plugging operations, gang the brake circuit’s electromagnetic contactors to the motor’s normal and reverse rotation
