Encoder is connected directly to the Speed Monitor.
What speed monitors are able to do
Safe monitoring of:
- Standstill
- Speed
- Speed range
- Direction
- Shaft break
- Belt misalignment
- Slippage
Even for different gear trains
- Break control
- Position
- End position
- Position range
Safety Gateways with Safe Fieldbus Connection
Safe speed monitoring in the drive
Motors with integrated Speed Monitor and safe fieldbus connection easily controlled using our Safety Gateway:
- CIP Safety via Sercos
- Safety over EtherCAT (FSoE)
Of course Bihl+Wiedemann also offers Safety Gateways for combining with a Safe PLC (F-CPU):
