When homing to a fixed stop:
1. Measure the distance between your reference point and
the retracted end position (Offset
Ref
; see Tab. 1/3).
2. Enter the value (± 1Ămm) in FCT or via the CI object
6410/16h.
Note
Controller inaccuracies
If you do not enter the offset of the reference point,
control inaccuracies (e.Ăg. overshooting) can occur with
small (100 mm) and large nominal strokes (400Ămm).
When homing to the drive’s integrated reference switch,
the reference point position is known (6 mm) and must not
be entered. This reference switch must not be moved.
Caution
Damage to components when the permissible impact
pulse is exceeded.
· Operate the drive only with the permitted load
(see operating instructions for the drive).
· If necessary, limit the maximum current (motor force)
during the reference run using:
Ĉ FCT ć or
Ĉ CI object 6073h Max. current".
