3.16 Axis couplings
Angle of the following axis
The angle of the following axis with respect to the path tangent depends on the transformation
ratio specified in TANG(...), the offset angle parameterized in the machine data MD37402
$MA_TANG_OFFSET, and the offset angle specified for TANGON(...), which is applied
additively.
Optimization "P"
If the value "P" was specified as the optimization parameter in the definition of the tangential
coupling (TANG(...)), the parameter "rounding clearance" and optionally the parameter
"angular tolerance" must be set when coupling is activated.
If the value 0 is specified as the angular tolerance, only the parameter "rounding clearance" will
be active.
If a value greater than 0 is specified as the angular tolerance, the active rounding clearance
results from the minimum of the parameterized rounding clearance and the rounding clearance
based on the parameterized angular tolerance.
If the dynamic response of the following axis is not sufficient to follow the parameterized
conditions, the path velocity of the leading axes will be reduced accordingly.
