Dynapar Series AD25 Drive Absolute Encoders

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.

Description

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.

 

Quick Specs…

  • For high performance BLDC Motors
  • Up to 22 Bit Single-turn Resolution
  • 4096 Revolutions of Multi-turn Resolution
  • Safety through self-diagnostics
  • Data storage on the encoder
  • Tapered Shaft
  • -15° C to +120° C Operating temperature

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.

 

Applications:

Fully digital position information with up to 22 Bit Single-turn + 12 Bit Multi-turn resolution for speed and position applications.
