5. Commissioning

5-14

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

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.
