rev 65534
This parameter is used to manage position information when an absolute encoder is used and an infinite length axis has been set.
Set it according to the setting of the encoder to be used.
•
Σ
Series: Always set to 99999.
•
Σ
-II or
Σ
-III Series: Set to the same value as the multiturn limit in the SERVOPACK.
For axes set as infinite axes (Function Selection 1 (fixed parameter 1), bit 0 set to 1), set to 65534 max.
(same value as Pn205).
This parameter is used to manage position information when an absolute encoder is used and an infinite length axis has been set.
No. 42
Feedback Speed Moving Average Time Constant
Setting Range Setting Unit Default Value
0 to 32 ms 10
The Feedback Speed (monitoring parameter IL
40) is the value obtained by calculating the moving average for the time
constant from the feedback position for every scan.
