Integrated Dual Absolute Encoder

  • Dual-Loop Position Control
  • Equipped with a 16-bit absolute multiturn encoder for the output shaft.
  • Achieves repeatability of up to ±7 arc seconds.
  • Delivers absolute accuracy of up to ±15 arc seconds.
  • Retains the true absolute position and multi-turn counter even during power loss.

Integrated Friction Brake

  • Provides smooth and stable braking performance.
  • No gaps or backlash, ensuring precise and reliable operation.
  • Does not require any movement upon power-on, ensuring immediate readiness. Designed with zero wear and tear, ensuring long-lasting durability.
  • It can be utilised as an emergency stop, providing an added layer of safety during critical situations.
