7 SYNCHRONOUS CONTROL
POINT
The actual deceleration time is longer than the set deceleration time if the output
axis speed is larger than the speed limit value.

(8) [Pr.447] Output axis smoothing time constant (D15070+150n)
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.
