Overview / Design Principle:
The ACURO AI25 is available in a single-turn or
multi-turn version. Its multi-turn design is based on
a reliable high-speed gear with optical scanning and
the latest generation of OptoASIC technology.
Mechanical concept is based on a double ball bearing
design, and is available as a solid-shaft or hollow-shaft
version in common shaft diameters.
BiSS is a new, fully-digital and bi-directional sensor
interface. It defines communication between one master
and several slaves (sensors) in industrial control systems.
BiSS manifests a new standard in technology and is available
license-free. Due to its high performance, it constitutes
an efficient alternative to the standard combination
of data interface and analog sine/cosine incremental
output.
BiSS needs only 6 wires and does not require any hardware
for analog signals - and therefore, helps to reduce
system costs.
Self-configuration allows "plug +
play" and keeps the system in an operable condition
even after a power failure. For detailed information
on BiSS and support, please visit www.biss-ic.de.
BiSS Benefits:
- All digital interface eliminates the costs of interpolation
electronics
- Offers transmission reliability through a 4-bit
cyclic redundancy check (CRC)
- Represents the only fully digital, open motor feedback
interface for real-time applications
