Measuring functions

After controller start-up, the measurement type specified in the channel parameter P-CHAN-00057 is specified. In the NC program, #MEAS MODE or #MEAS [TYPE..] can be used at any time to select a new measurement type.

In the NC program, the variable V.G.MEAS_TYPE supplies the currently valid measurement type. The following 7 measurement types are available:

Measurement type

Meaning

1*

Measurement run with at least one axis,
measuring feed programmable via F word.

2*

Measurement run with exactly one axis,
measuring feed is defined in P-AXIS-00215.

An error message is output if the probe signal is missing.

3

Measurement run with at least one axis,
measuring feed programmable via F word,
optionally with continued motion up to the target point.

4

Measurement run only with maximum 3 main axes,
measuring feed programmable via F word.

5

Interruptible measurement run with at least one axis,
measuring feed programmable via F word.

6

Interruptible measurement run with at least one SERCOS axis,
measuring feed programmable via F word.

7*

Measurement run with motion to a fixed stop with at least one axis, measuring feed programmable via F word.

* with these measurement types, a measurement run is also possible using independent axes.

The following variables related to the measurement run are available in the NC program (see also Section Axis-specific variables (V.A) ).

Only the variable values of the axes programmed during the measurement run are updated. All other axis-specific measuring variables retain the old values or 0.

V.A.MERF.<axis>

Measurement run completed?

V.A.MESS.<axis>

Supplies the axis-specific measuring value in [mm, inch] after a measurement run in which the measurement took place. The value always includes all offsets in the calculation.

With 2.5D: ACS values or with CS / TRAFO: PCS values

V.A.MOFFS.<axis>

Measuring offset in [mm, inch]

V.A.MEIN.<axis>

Measuring offset calculated in [mm, inch]

As of Build V2.11.2020.07

V.A.MEAS.ACS.VALUE.<axis>

Measurement value in the axis coordinate system in [mm, inch] including all offsets.

V.A.MEAS.PCS.VALUE.<axis>

Measured value in the coordinate programming system in [mm, inch] without offsets.

Restrictions:

A measurement run cannot be programmed if:
