INCREMENT
[Function]
When manual feedrate is specified in file register mode (JVS: "ON") or in random manual feed
mode, file registers R (R904 and R905) are used. In this case, least increment of feedrate entered
into file registers R904 and R905 is specified by this signal.
[Operation]
The relationship between PCF1/PCF2 and least feed increment is as follows:
PCF2 PCF1
(mm/min or inch/min)
0 0
0 1
1 0
1 1
