Problem
Possible Causes
Solution
No or limited
motion
The cable is not
connected correctly
Check the cable connections.
Excessive load
Do
not
exceed the maximum permissible
stress and load capacities according to
the specifications (p. 39).
Zero shift of the
sensor for the
following reasons:
Load applied in
direction of motion
Ambient/operating
temperature of the
stage far above or
below calibration
temperature
(21 °C to 24 °C)
Perform a zero-point adjustment of the
sensor (see controller manual).
Reduced
positioning
accuracy
Warping of the base
body or the moving
platform
Only mount the P-56x on surfaces with
the following characteristics:
−
Evenness of at least 20
μm
−
The thermal expansion properties are
similar to those of the P-56x (e. g.
surfaces made of aluminum).
Only affix loads with the following
characteristics on the P-56x:
−
The contact surface of the load has an
evenness of at least 20
μm.
−
The thermal expansion properties are
similar to those of the P-56x (e. g.
loads made of aluminum).
