Exact stop criteria "Exact stop coarse" and "Exact stop fine".

The exact stop criteria "Exact stop coarse" and "Exact stop fine" are used to specify tolerance

windows for a machine axis reaching the "exact stop" state.

Parameters are assigned to the two exact stop criteria via the machine data:

MD36010 $MA_STOP_LIMIT_FINE (exact stop fine)

MD36000 $MA_STOP_LIMIT_COARSE (exact stop coarse)

The tolerance windows of the exact stop criteria "Exact stop coarse" and "Exact stop fine"

should be assigned in such a way that the following requirement is fulfilled:

"Exact stop coarse" > "Exact stop fine"

Exact stop criterion "Interpolator End"

In the case of the exact stop criterion "interpolator end" the block change to the next traversing

block takes place, as soon as all path axes and special axes involved in the traversing motion,

which do not traverse extending up to block, have reached their position according to set point

programmed in the block. That is, the interpolator has executed the block.

The actual position and the following error of the relevant machine axes are not taken into

consideration for exact stop criterion "Interpolator end". Thus, depending on the dynamic

response of the machine axes, this can result in a relatively large smoothing of the contour at

the block changes in comparison to the exact stop criteria "Exact stop coarse" and "Exact stop
