MC-Basic:axis.PositionBacklashAlpha
Value of the alpha filter used in backlash compensation. It is used to eliminate strong jumping of backlash compensation value between positive and negative directions, typically occurring near target point or at the beginning of the movement. See <axis>.PositionBacklash and <comp>.Direction.
- Bigger values (close to 1.0) are for sharper corners (faster response)
- Smaller values (close to 0.1) are for smoother behavior
Picture showing different values of backlash compensation in different movement directions. Note the influence of PositionBacklashAlpha factor (0.9, 0.95, 0.99)
