} Tab. 1/3).
2. Enter the value (±1Ămm) in FCT or via the CI object
6410/16h / PNU 1055.
Note
Controller inaccuracies
If you do not enter the offset of the reference point, control
inaccuracies (e.g. overshooting) can occur with small
(100Ămm) 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:
