Applications

Incremental HeavyDuty encoders provide information on speed and angular position. Their resolution is expressed as the number of pulses (square-wave signals) and the sinusoidal (SinCos) signals per revolution, which the rotary encoder transmits to the controller with each revolution of its shaft. SinCos signals can be interpolated in a controller or in a controller to increase the resolution.

The upstream control identifies the current speed by the pulse numbers counted within a defined time period, while the current position information is identified by the counted pulses or SinCos periods, respectively. At system power-on, a reference travel is required since the encoder information may have been lost during power off and further to eliminate any incorrect result caused by any shaft rotation performed during power-off.

Incremental HeavyDuty encoders are designed for maximum robustness and durability, with enormous mechanical reserves to ensure reliable performance even in the harshest environments:

  • Steelworks and rolling mills
  • Port installations and crane technology
  • Hoists and lifting platforms
  • Underground and open pit mining
  • Materials handling equipment
  • Large drives and generators
  • Wind turbines
