Filter type for smoothing sensor values (P-AXIS-00782)

P-AXIS-00782

Filter type for smoothing sensor values

Description

In some cases, the sensor values are noisy. The oscillation tendency can be possibly suppressed by using a suitable filter . The following filter types can be selected for distance control:

  • DEFAULT: Moving average filter where P-AXIS-00413 = 4
  • MOVING_AVERAGE: Moving average filter
  • LOWPASS Low-pass filter
  • KALMAN_MA: Kalman filter with prediction from average filter
  • EXPO_MEAN: Exponential weighted average filter
  • KALMAN_EXPO: Kalman filter with prediction from exponentially weighted average filter
