5. Commissioning

After a successful homing the drive stops at the axis zero
point AZ. With first commissioning or when the homing
method is changed, the offset of the axis zero point = 0; after
homing the drive then stands at the homing point REF.

Discontinuing homing

If necessary, homing can be discontinued with the <Menu>
button (EMERG STOP). If correct homing has already been
carried out, the previous homing point will retain its validity.

Error in the homing run

If the axis does not find a reference switch during homing, it
keeps moving until it encounters a stop. Then it comes to rest
at the stop and HOMING ERROR is displayed. Homing must
be repeated after resetting the error message:

Reasons for this may be:

Axis already positioned behind reference switch at start of
homing,

Reference switch defective,

Axis defective or incorrectly mounted, e.g. clutch attach-
ment slipping.
