Applies to Fanuc 31:
Parameter 1601 #4 RTP = 0 Blocks are overlapped in Rapid Traverse 1 Blocks are not overlapped
Parameter 1601 #5 NCI= 0 Confirms that the specified feedrate becomes
0 (the accel/decel delay becomes 0) at delcelaration time and that the machine position has reached a specified position (the servo positional deviation is within the in-position width set by parameters #1872.Parameter 1601 #5NCI= 1 Confirms only that the specified feedrate becomes 0 (the accelaration/deceleration delay becomes 0)at decel. time.
Parameter 1722 = Rapid Traverse feedrate ratio for overlapping rapid blocks.
Only one parameter determines the "In position zone" 1872, this actually applies to all Fanucs (not always the same parameter #)
There are quite a few parameters that describe acel/decel/time constants for contouring, threading, corners...........blah blah blah
The description that KG wrote is the way it works
