Problem
Possible causes
Solution
No or limited
motion
Cable not connected
correctly
Check the cable connections.
Excessive load
Do
not
exceed the maximum permissible
stress and load capacities according to
the specifications (p. 41).
Zero shift of the sensor for
the following reasons:
Load in direction of
motion
Ambient/operating
temperature of the
positioner is far above
or below the calibration
temperature (21 °C to
24 °C)
Adjust the zero-point of the sensor (see
controller manual).
Reduced accuracy The base body or the
platform is distorted
Mount the P-62x onto surfaces with the
following characteristics only:
−
Flatness of at least 20
μm
−
The thermal expansion properties are
similar to those of the P-62x (e.g.,
surfaces made of aluminum).
Mount loads onto the P-62x with the
following characteristics only:
−
The contact surface of the load has a
flatness of at least 20
μm.
−
The thermal expansion properties are
similar to those of the P-62x (e.g.,
loads made of aluminum).
P-62x or controller has been
replaced
When using positioners where the ID chip
does not contain any calibration data, or
LEMO plug connectors, axis displacement has
to be recalibrated after the P-62x or the
controller has been replaced.
Recalibrate the axis displacement (see
controller manual) or contact our
customer service department (p. 39).
