Z or E Active exact stop criterion
0 Programmed exact stop criterion
1 G601 (Exact stop window fine)
2 G602 (Exact stop window coarse)
3 G603 (Interpolator end)
Example
MD20550 $MC_EXACT_POS_MODE = 02
Ones position = 2:
With rapid traverse, exact stop criterion G602 (Exact stop window coarse) is always active, irrespective of any
programming in the parts program.
Tens digit = 0:
For traversing with all other parts program commands of the first G function group, the exact stop criterion
programmed in the parts program is active.
Assignable exact stop criterion for rapid traverse transitions in continuous path mode
The behavior at the block transition of part program blocks before and after rapid traverse blocks can be
parameterized as follows:
MD20552 $MC_EXACT_POS_MODE_G0_TO_G1 = <value>
Value Meaning
0 No additional stop at the block transition.
1 Stop at block transition: Same behavior as in the case of G601 (Exact stop window fine)
2 Stop at block transition: Same behavior as G602 (Exact stop window coarse).
3 Stop at block transition: Same behavior as G603 (Interpolator end).
4 Like 0, in addition, the override of the next non-G0 block is taken into account with
LookAhead in the G0 block during the transition from G0 to non-G0.
5 Like 0; in addition, the override of the next block is taken into account with LookAhead during
the transition from G0 to non-G0 and from non-G0 to G0.
