Overview / Design Principle:
The Acuro AD25 is an optical absolute encoder with
an optical multi-turn gearbox (non magnetic). Double
ball bearing design with flexible spring tether as a
torque support. Designed for integration into BLDC servomotors
for demanding applications such as CNC, precision positioning
and high quality printing. Low current consumption of
85 mA contributes to lowering the drive cost.
The AD25 features new, fully digital technology …
Conventional top of the range absolute encoders for
motor feedback still provide analog sinusoidal signals
to feedback the speed and position of the motor. This
information is transmitted over a bidirectional synchronous
interface with a variable clock rate up to 10 MHz, resulting
in over 4 million measuring steps.
BiSS Interface
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, does not require any hardware
for analog signals (cables and drive interpolation electronics)
- and therefore, helps to reduce system costs.
Self-configuration capabilities allow "plug +
play" and keep the system in an operable condition even
after a power failure. For more detailed information
