Programming “traverse to a fixed stop”:
U Position the slide at a sufficient distance before the fixed stop.
U Use a moderate feed rate (< 1000 mm/min)
U Program G916 or G916 Hx D1 in the G1 positioning block
U Program G1 .. as follows:
„ Target position is behind the fixed stop
„ Move only one axis
„ Activate a per-minute feed rate (G94)
Example of traversing to a fixed stop:
Tailstock function (G916 with parameters)
„ G916 Hx D1 activates the tailstock function. The CNC PILOT
„ moves up to the workpiece and stops as soon as the contact force
has been reached.
„ deletes the remaining path of traverse
„ G916 D2 deactivates the tailstock function. The CNC PILOT
„ deactivates the tailstock function.
„ moves back by the servo lag + reversing path (MP 1112, 1162, ..)
G916 D2 can be combined with a G1 positioning block
