6-6 Points to Note When Using a Quick Braking Circuit
When using brakes with quick braking circuits, take note of the following items.
- Connect a varistor (protection element) to protect the quick braking circuit contact points from surge voltage generated by the brake action.
- Wire the quick braking circuit contact points to the brake power source secondary side contact points. Contact points might not be protected.
- For information on using an alternating current electromagnetic contactor for contact points for quick braking circuits, see Table 6-4.
If multiple contact points are required, note the following issues.
- Connect electromagnetic contactor contact points in serial. (See gure 6-3)
- Connect the varistor (VR) as close to the unit as possible. (See gure 6-3)

- This recommended contactor nomenclature is for Fuji Electric FA Components & Systems Co., Ltd. and Mitsubishi Electric Corporation contactors. Products from
other manufacturers are also allowable if they have equivalent capabilities.
- Recommended contactor contact point capacity indicates the case where durability regarding electronic opening and closing (service life) is approximately
2million times (for FB-30, ESB-250 and ESB-250-2, approximately 1million times).
- Of the recommended contactors, the Mitsubishi Electric Corporation S-N11 has one auxiliary contact point; the S-N18 has none. This applies if, for inverter drive or
other reasons, two or more auxiliary contact points are required. (Other connectors in Table 6-4 have two or more auxiliary contact points.)
- This recommended varistor nomenclature is for Nippon Chemi-Con Corporation varistors. Products from other manufacturers are also allowable if they have
equivalent capabilities.
- In the FB-20, FB-30, ESB-250 and ESB-250-2, a varistor for protecting the connector contact points is built in to the rectier.
