4.11 Configuration of axes − speed and acceleration
There are different MCs which influence the maximum speeds and ramps for
the individual axes and for the paths resulting thereof. These are the limit
values that must not be exceeded by the control. The axis−specific MCs are
effective in path, route and manual operation. The path−specific MCs only
act as limit values in path operation.
4.11.1 MK_MODVMAX
This machine constant is the maximum speed for manual operation
(traverse buttons) of the individual axes. The specified value is limited to
MK_VMAX.
4.11.2 MK_VMAX
This machine constant is the maximum permissible speed of the individual
axes in [m/min] or [1/min]. This corresponds the high−rate speed of the axes
in route operation. Also the traversing speed in path operation is limited by
the control, if possible, to such an extent that the maximum speed of the
individual axes is not exceeded.

Note!
In the case of some transformations, such as basic/profile
rotation and 6−axes transformation, the control cannot limit the
material speed because, seen logically, the transformation takes
place after the path interpolation and the die speed of the axes
cannot be determined beforehand.
4.11.3 MK_BESCHL, MK_BREMS
These machine constants define the maximum acceleration and
deceleration ramps of the individual axes in [m/s
2 ] or [1/s 2 ]. During path
operation, the path ramps are limited in proportion in accordance with the
involvement of the individual axes.
4.11.4 MK_T_BESCHL
This machine constant is the time in milliseconds, in which the maximum
ramps configured in MK_BESCHL and MK_BREMS are to be reached in
manual operation and route operation. This MC is used to set acceleration
ramps and deceleration ramps of the individual axes that are similar to sin
2
ramps.
