What is BiSS

1
What is BiSS?

• Introduced at Hannover April 2002
• Today there are more than 120 OEM licensees
• Open standard, non-proprietary protocol
• Fast, safe, synchronous serial 2-wire link (10
  Mbit/s)
• Isochronous real-time data acquisition
• Efficient transmission
• Networking capable 8 devices per master

Industrial control systems overview
Motor control is only as good as the
motor-to-drive feedback
3
The Evolution of Precision Control

• Incremental
• Resolver
• Absolute Sin/Cos
• Absolute High Speed Digital Serial

4
Achieving Superior Motor Feedback

• A wish-list of items that are most desirable in a
  perfect system.
• Non-proprietary encoder protocol
• Instantaneous updates on encoder position
• Precision beyond the mechanical capability of the
  system
• Noise immunity over long cable runs
• Reduced total cost of ownership (cables, drives,
  electronics)
