  Absolute encoder, incremental encoders and accessories

  The built-on optoelectronic rotary encoders measure paths, angles of rotation or speeds in machines. They can be used in conjunction with computerized numerical controls, programmable logic controllers, drives and position displays, e.g. for:

  • SINUMERIK CNC controls
  • SIMOTION Motion Control Systems
  • SIMATIC programmable logic controllers
  • SINAMICS drive systems

  Область применения

  A distinction is made between incremental and absolute measuring procedures:

  • In the case of incremental encoders, the machine must travel to a reference point after each power‑off state, as the position is not usually stored in the controller, and movements of the machine while the power is off are not recorded.
  • Absolute encoders, on the other hand, also record these movements while the power is off and return the actual position with power On. Travel to a reference point is not necessary.

  Дизайн

  All encoders are available in Synchro flange and clamp flange versions. Encoders with a Synchro flange can be attached to the machine with 3 clamps or mounted with axial screws. The encoder is driven by means of a plug‑in coupling or a spring disk coupling. Alternatively, pulleys can also be used.

  The encoder supply voltage is 5 V DC or alternatively 10 V to 30 V DC. The 10 V to 30 V DC version supports longer cable lengths. Most control systems apply the supply voltage directly at the measuring circuit connector. With SINAMICS, the power supply for the measuring systems is provided via the Sensor Modules.

  For rotary encoders with cables, the cable length including the connector is 1 m (3.28 ft).

  The following bending radii for the cables at the encoder must be observed:

  • One‑time bending: ≥ 20 mm (0.79 in)
  • Continuous bending: ≥ 75 mm (2.95 in)
