Parameterization - Siemens SINUMERIK 828D Function Manual

Path acceleration =
(1 - MD20602 $MC_CURV_EFFECT_ON_PATH_ACCEL) * MD32300
$MA_MAX_AX_ACCEL
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:
The acceleration margin is set as follows:
Linear motions
The acceleration margin referred to above is ineffective in the case of linear motions (linear interpolation) without
active kinematic transformation.

Parameterization

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)
