traversing of the
reference marks Module 9220 Traverse reference mark
The module starts the reference mark traverse in an axis or servo-controlled
spindle. If the reference mark has already been evaluated, it can be evaluated
again by this module. The module can be called in all operating modes.
Constraints:

Software limit switches are not effective.

The sequence of functions is determined by MP_refType.

The velocity and the direction for traversing the reference marks are either
taken from
MP_CfgReferencing /refFeedHigh and
MP_CfgReferencing/refDirection or they are defined in the module.

An axis cannot be started for referencing until all other axes are in position.

If an axis is started for reference point traverse although the reference mark
has already been traversed, NN_AxReferenceAvailable is reset and the ref-
erence mark is evaluated again. The same constraints apply as when tra-
versing the reference mark for the first time.

If the spindle is started for reference point traverse, marker
NN_SpiReferenceAvailable is set.

The spindle must be started from a standstill to traverse the reference mark.
Call:
ps
b/w/d/k <Axis/spindle>
Index from MP_CfgAxes/axisList
ps b/w/d/k <Feed rate / rotational speed>
0: Feed rate / rpm from MP_CfgReferencing/refFeedHigh
>0: Feed rate in mm/min or rotational speed in 1/1000 rpm
ps b/w/d/k <Direction of traverse>
–1: Negative direction
0: Direction from MP_CfgReferencing/refDirection
1: Positive direction
cm 9220
pl b/w/d <Error code>
0: Reference mark traverse is commanded
1: Axis does not exist, or not a servo-controlled spindle
2: Illegal values for the feed rate / direction
3: Incorrect operating mode
4: Reference traverse already started
5: Axis is already being positioned or the spindle is in motion
6: Other axis is already being positioned
8: Programmed axis not in closed loop
Note
The direction of traverse should be defined in the module only in exceptio-
nal cases. Since the reference end position is not considered in this case,
the limits of the traverse range may be violated.
