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.

Description: Configuration of the exact stop conditions for G00 and other G codes of the 1st G code
group.
The MD is decimal-coded. The units digits define the behavior at G00 (infeed motion)
and the tens
digits the behavior of all the other G codes of the 1st group ("machining
G codes").
x0: At G00, the relevant programmed exact stop conditions become active.
x1: At G00, G601 (fine positioning window) becomes active independent of the
programmed exact stop condition.
x2: At G00, G602 (coarse positioning window) becomes active independent of the
programmed exact stop condition.
x3: At G00, G603 (setpoint value reached) becomes active independent of the
programmed exact stop condition.
0x: At the machining G codes, the relevant programmed exact stop conditions become
active.
