When using a PT1 speed setpoint smoothing filter (drive MD 1502* or 1503*), the value
entered there must be entered under NC MD 3420*.
By gradually adjusting the input value NC MD 3420* (up or down), a setting can be found
resulting in still further reduced contour deviation during acceleration or deceleration
processes.
