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
<Menu> 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.”
