FFB
Failsafe brake operating when supply off (a braking force is applied when de-energized) on LS non-IE, IE3 asynchronous three-phase IMfinity® motors range.
Advantages
- Reliability and robustness
- Performance and safety
- Flexible conception
- Supervision on brake duties: wear indicator microswitch, tightening and loosening indicator microswitch
- Auto-return brake release systems: simple, lock off or remote lever
- Variable speed construction: thermal protection, encoder and/or forced ventilation
