6.7.2 Traversing the reference marks

Distance between

the scale reference

point and the

machine datum

The reference marks must be traversed after any interruption in power:

Press the machine START button: The reference marks are automatically

traversed. The sequence of axes is predetermined.

Press the machine axis-direction button. The user determines the sequence

of the axes.

After the reference marks have been traversed:

The software limit switches are activated.

The most recently saved datum and machine datum are reproduced.

PLC positioning and positioning with M91 and M92 become possible.

The counter is set to zero for axes in an open loop.

For position encoders with distance-coded reference marks, the machine

datum is defined with respect to the scale reference point, which is at the first

reference mark after the beginning of the measuring length. On angle

encoders, the scale reference point is marked.

In MP960.x, enter the distance between the scale reference point and the

machine datum.

For position encoders without distance-coded reference marks but with more

than one reference mark, the distance between the reference mark to be

traversed and the scale reference point must also be entered:

With Module 9225, enter the distance between the reference mark to be

traversed and the scale reference point.

With Module 9225 you define the distance between the reference mark to be

traversed and the scale reference point for the NC and PLC axes.

B/W/D/K <Axis>

0 to 8: Axes 1 to 9

B/W/D/K <Compensation value in 0.1 µm>

0: Reference mark to be traversed = scale reference point

1: Axis does not exist

Axis not found
