Set the average movement time of speed command smoothing filter.
It can be used when No.77.0 is effective.

Set the position command smoothing filter 1 to “1(Used)” in No.66.0 to make No.80.0
valid.
Set the position command smoothing filter 2 to “1(Used)” in No.66.1 to make No.81.0
valid.
When the setting value of average movement number increases, the acceleration/
deceleration will be smooth, but the response will be slow.
Setting filter 1, the average movement number can be set between 1 and 6250; setting
filter 2, the average movement number can be set between 1 and 1250.
The average movement time can be represented by the following formula.
200
～
750W
：
(average movement time)=(average movement number) ×0.16ms
1k
～
2kW: (average movement time)=(average movement number) ×0.2ms
[Adjustment method]
●
Smoothing will make positioning time longer in response to above average
movement time. Please have settings within the permissible range..
●
When resonant occurs at constant move after acceleration or positioning after
deceleration, measuring the resonant frequency in torque command curve and setting
a corresponding average movement number in position command smoothing filter1
moving average time No,80 or position command smoothing filter2 average
movement number No.81, may inhibit resonance. The calculation of average
movement number and its corresponding suppressed resonance frequency is shown
below.
750W or less: Setting value of smoothing filter=6250/(suppressed vibration
frequency[Hz])
1kW or more: Setting value of smoothing filter=5000/(suppressed vibration

●
The vibration caused by gain FF compensation 2 can be suppressed by position
command smoothing filter 2.
When using gain FF compensation 2 No.117.0, vibration can be reduced by using the
average movement number of position command smoothing filter 1 and filter 2.
[Notes] This parameter can be set when the command pulse input is “0” for more
than 1.5s and there is no command pulse input. If possible, it is recommended to turn
off the servo. If you set the parameter when there is pulse input or residual pulse,
Yes
