[Pr.447] Output axis smoothing time constant
Set the averaging time to execute a smoothing process for the travel value of the output
axis after cam data conversion.
The smoothing process can moderate sudden speed fluctuation for cams using the
coordinate data format, etc.
The input response is delayed depending on the time corresponding to the setting by
smoothing process setting.
