2.4 Acceleration margin (channel-specific)
2.4.1 Detailed Description
2.4.1.1 General Information
General information
Under normal circumstances, preprocessing makes maximum use of the parameterized
maximum values of the machine axes for the purpose of path acceleration. In order that an
acceleration margin may be set aside for overlaid movements, e.g., within the context of the
"Rapid lift away from the contour" function, path acceleration can be reduced by a
programmable factor. When, for example, a factor of 0.2 is applied, preprocessing will only
use 80% of the maximum possible path acceleration. 20% is set aside as an acceleration
margin for overlaid movements.
2.4.2 Activation
2.4.2.1 Parameterization
Parameterization
Parameters for the acceleration margin are assigned for each channel by means of machine
datum:
MD20610 $MC_ADD_MOVE_ACCEL_RESERVE
(acceleration margin for overlaid motions)
2.4.3 Programming
The function is not programmable.
