Application of Encoders HOG9 / POG9

 

  • 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 (Sin/Cos) signals per revolution, which the rotary encoder transmits to the controller with each revolution of its shaft. Sin/Cos 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 period, while the current position information is identified by the counted pulses or Sin/Cos periods, respectively. At system power-on, 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.
