2.5.5 Phase 2: Travel to fixed stop
Phase 2: Start
Phase 2 is automatically started when phase 1 has been completed without an alarm.
Initial situation:
• The machine axis is positioned directly behind the last of the parameterized number of
reference marks.
• The actual value system of the machine axis is synchronized.
Phase 2: Sequence
In Phase 2, the machine axis completes reference point approach by traversing to a defined
target position (reference point). This action can be suppressed in order to shorten the
reference point approach:
MD34330 $MA_STOP_AT_ABS_MARKER =
Mode
Mode = 0: Travel to target position
Mode = 1: No travel to target position
Mode = 0: Travel to target position (normal case)
The machine axis accelerates to the assigned reference point positioning velocity:
MD34070 $MA_REFP_VELO_POS
and moves to the assigned end point (reference point):
MD34100 $MA_REFP_SET_POS (reference point value).
The machine axis is referenced. To identify this, the NC sets an interface signal for the
measuring system that is currently active:
DB31, ... DBB60.4/60.5 (referenced/synchronized 1/2) = 1
Mode = 1: No travel to target position
The machine axis is now referenced. To identify this, the NC sets an interface signal for the
measuring system that is currently active:
DB31, ... DBB60.4/60.5 (referenced/synchronized 1/2) = 1
