5 INPUT AXIS MODULE
(2) [Pr.301] Servo input axis smoothing time constant
Set the averaging time to execute a smoothing process for the input travel value
from the servo input axis.
The smoothing process can moderate speed fluctuation, when the "Real current
value" or "Feedback value" is used as input values.
The input response is delayed depending on the time corresponding to the
setting by smoothing process setting.

(3) [Pr.302] Servo input axis phase compensation advance time
(D14600+2n, D14601+2n)
Set the time to advance or delay the phase (input response) of the servo input
axis.
Refer to Section 8.1 for the peculiar time delay of the system using the servo
input axis.
• 1 to 2147483647 [μs] ..........Advance the phase (input response) according to
• 0 [μs]....................................Do not execute phase compensation.
• -2147483648 to -1 [μs]........Delay the phase (input response) according to the
If the setting time is too long, the system experiences overshoot or undershoot at
acceleration/deceleration of the input speed. In this case, set longer time to affect
