December 2001 Contouring Behavior 6 – 155
If you have set bit 8, you can specify with bit 9 whether the jerk will remain
constant on the spline. The contour speed is adjusted for constant jerk.
If you program M132, you can reduce the jerk on the contour for changes of
acceleration in individual axes. M133 switches M132 off.
MP7460 Angle for constant contour speed at corners
Input: 0.0001 to 179.9999 [°]
MP7680 Machine parameter with multiple function
Format: %xxxxxxxxxxxxx
Input: Bit 7 – Inserting a defined rounding arc or spline:
0: Defined rounding arcs are always inserted
1: Defined rounding arcs are always inserted if the acceleration
from MP1060.x or MP1070 was exceeded.
Bit 8 – Insertion of rounding arc or cubic spline:
0: Rounding arc is inserted.
1: A cubic spline is inserted instead of a rounding arc.
Bit 9 – Constant jerk on spline (Bit 8 = 1):
0: No constant jerk
1: Constant jerk
