Parameterization

Path axis
Parameter assignment
The parameterization of the axis-specific velocity limit, above which the reduced acceleration
acts as an axis for traversing movements, is done via the machine data:
MD35220 $MA_ACCEL_REDUCTION_SPEED_POINT = <speed limit>
Single axis
Activation
The activation of the axis-specific velocity limit, above which the reduced acceleration acts as
a single axis for traversing movements, is done via machine data:
MD35240 $MA_ACCEL_TYPE_DRIVE = TRUE
