After successful reference travel the drive stands at the axis
zero point AZ. On initial commissioning or following a change
of homing method the axis zero offset is = 0; after homing the
drive is then positioned at the reference point (REF).

Discontinue reference travel

If necessary, reference travel can be discontinued with the

button (EMERG STOP). If correct referencing has
already been carried out, the previous reference point will
retain its validity.

Error in the reference run

If the axis cannot find a reference switch during reference
travel, it will move until it strikes a stop. It will then remain at
the stop and the fault HOMING ERROR is displayed. The refer-
ence run must be repeated after the error message has been
acknowledged:

The reasons for this can be:

–

At the start of reference travel, the axis already stands
behind the reference switch.

–

The reference switch is defective.

–

The axis is defective or fitted incorrectly, e. g. the coupling
“does not grip.”
