Basic logic functions: Acceleration (B2)

Example
The following machine parameters apply:
• MD32300 $MA_MAX_AX_ACCEL for all geometry axes: 3 m/s
• Maximum path velocity with a path radius of 10 mm due to mechanical constraints of the
machine: 5 m/min.
The radial acceleration is calculated as follows:
D
UDGLDO
Y
SDWK
>PPLQ@
U>PP@>PV
@
PV
The acceleration margin is set as follows:
0'0&B&859B())(&7B21B3$7+B$&&(/
D

Linear motions
The acceleration margin referred to above is ineffective in the case of linear motions (linear
interpolation) without active kinematic transformation.
2.10.2 Activation
2.10.2.1 Parameterization
Function
The proportion of maximum available axis acceleration to be taken into account as an
acceleration margin for radial acceleration on curved contours is parameterized using the
channel-specific machine data:
MD20602 $MC_CURV_EFFECT_ON_PATH_ACCEL
(influence of path curvature on dynamic path response)
2.10.3 Programming
Programmability
The function is not programmable.
