2.9 Excessive acceleration for non-tangential block transitions (axis-
specific)
2.9.1 Detailed Description
2.9.1.1 General Information
Function
In the case of non-tangential block transitions (corners), the programmable controller may
have to decelerate the geometry axes significantly in order to ensure compliance with the
parameterized axis dynamics. For the purpose of reducing/avoiding deceleration in
connection with non-tangential block transitions, a higher level of axis-specific acceleration
can be enabled.
Excessive acceleration is parameterized using a factor calculated in relation to the axis-
specific maximum value. This is used to generate the maximum value for axis-specific
acceleration with non-tangential block transitions that is taken into account by the path
planning component during preprocessing:
Acceleration[axis] =
MD32300 $MA_MAX_AX_ACCEL * MD32310 $MA_MAX_ACCEL_OVL_FACTOR
2.9.2 Activation
2.9.2.1 Parameterization
Function
Excessive acceleration for non-tangential block transitions is parameterized using the axis-
specific machine data:
MD32310 $MA_MAX_ACCEL_OVL_FACTOR
(overload factor for velocity jumps)
2.9.3 Programming
Programmability
The function is not programmable.
