Validity
The function is configured only for the first channel.
Braking behavior
Braking behavior at the SW limit with path axes
The programmable acceleration factor ACC for braking at the SW limit corresponds to the path
axes.
The axes in an MCS coupling are principal axes that are referred to as geometry axes due to
their geometric arrangement.
Braking geometry axes using synchronized actions
The faster deceleration capacity as required for path axes can be implemented for geometry
axes as follows using a synchronized action:
ACC[x2]=190
Axial acceleration limitation with G0
The following machine data is not considered by the MCS coupling:
MD32434 $MA_G00_ACCEL_FACTOR (scaling of the acceleration limitation with G0)
A value deviating from the standard value affects the braking ramp up to the software limit
switch.
