4.2 Approaching a reference point

Approaching a reference point

Your machine tool can be equipped with an absolute or incremental path measuring system.

An axis with incremental path measuring system must be referenced after the controller has

been switched on – however, an absolute path measuring system does not have to be

For the incremental path measuring system, all the machine axes must therefore first approach

a reference point, the coordinates of which are known to be relative to the machine zero-point.

Prior to the approach, the axes must be in a position from where they can approach the

reference point without a collision.

The axes can also all approach the reference point simultaneously, depending on the

manufacturer's settings.

Risk of collision

If the axes are not in a collision-free position, you must first traverse them to safe positions

in "JOG" or "MDI" mode.

You must follow the axis motions directly on the machine!

Ignore the actual value display until the axes have been referenced!

The software limit switches are not active!

Machine manufacturer

Please refer to the machine manufacturer's specifications.
