NOTE
*1 This is not available for Machining (M series).
(2) The override at extracting.
5200 #4
0 : The override at extracting is not valid.
1 : The override at extracting is valid.
(Set override value at No. 5211)
[Series 30i]
(1) Each parameter can be set for each gear and is selected according
to the gear selection signal.
By setting the following parameter, the different time constant
between the cutting in and cutting out (extracting) becomes
available.
5201 #2
0 : The same time constant between cutting in and out.
(No. 5261 to 5264)
1 : The different time constant between cutting in and
out.
Cutting in : No. 5261 to 5264
Cutting out: No. 5271 to 5274
