You can set two different speeds for searching for the
reference point and for the subsequent run to the axis zero
point. The maximum possible speed is subject to built−in
limits.
The reference travel sequence is described in section 1.4.
When referencing to a fixed stop
1. Measure the distance between your reference point and
the retracted end position (Offset
Ref
see Tab.1/4).
2. Enter the value (±1mm) in FCT or
via the object 6410/16h / PNU 1055.
Note
Control inaccuracies
If you do not enter the offset of the reference point, control
inaccuracies (e. g. overshooting) can occur with small
(100mm) and large nominal strokes (400mm).
During reference travel to the reference switch the position
of the reference point is known (6 mm) and does not need
to be entered. The reference switch must not be moved.
Caution
Damage to components if the permitted stop pulse is
exceeded.
·
Operate the HME−... only with the permitted mass
(seeoperating instructions for HME−...).
·
If necessary, limit the maximum current (motor force)
during the reference run using:
FCT or
CI object 6073h / PNU 1034 Max. current".
