Description: This MD is used to determine the settings for spline interpolation. The allocation of
the spline segments to the NC blocks can thus be influenced. With spline
interpolation, the spline
blocks are combined, if possible, in such a way, that there
are no blocks that are too short and could lead to a reduction in the possible path
velocity.
Bit 0: With BSPLINE, blocks that are too short are avoided.
Bit 1: With BSPLINE/ORICURVE, blocks that are too short are avoided.
Bit 2: With CSPLINE, blocks that are too short are avoided.

Description: A block transition is normally only smoothed with G64x when the path velocity at block
transition is reduced
by the overload factor set in MD32310 $MA_MAX_ACCEL_OVL_FACTOR.
When SOFT is active, the maximum jerk occurring at block transitions is also limited
by MD32432 $MA_PATH_TRANS_JERK_LIM. This means that the effect of smoothing with G64x
depends on the values set for the overload factor and possibly for the maximum jerk.
By setting MD20490 $MC_IGNORE_OVL_FACTOR_FOR_ADIS = TRUE, a block transition can be
smoothed with G64x, irrespectively of the values set for the overload factor.

Description: Defines the minimum time for constant velocity during transition from acceleration to
deceleration in short blocks in which the set velocity cannot be reached. Entering a
time
of
at
least several IPO cycles prevents a direct transition from the acceleration
to the deceleration phase and thus reduces the acceleration jump to half. This
acceleration limitation is only active with the acceleration profile BRISK.
