Description
Master value coupling requires synchronization of the leading and the following axes. This
synchronization can only be achieved if the following axis is inside the tolerance range of the
curve definition calculated from the curve table when the master value coupling is activated.
The tolerance range for the position of the following axis is defined via machine data MD
37200: COUPLE_POS_POL_COARSE A_LEAD_TYPE.
