Solution
 Check the cable connections.
 Do not exceed the maximum permissible
stress and load capacities according to
the specifications (p. 37).
 Adjust the zero-point of the sensor (refer
to the controller manual).
 Mount the P-73x onto surfaces with the
following characteristics only:
− Flatness of at least 20 μm
− The thermal expansion properties are
similar to those of the P-73x (e.g.,
surface made of aluminum).
 Mount loads onto the P-73x 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-73x (e.g.,
load made of aluminum).
When using positioners with an ID chip (p. 15)
that does not contain any calibration data, or
with LEMO plug connectors, axis
displacement has to be recalibrated after the
P-73x or the controller has been replaced.
 Recalibrate the axis displacement (refer
to the controller manual) or contact our
customer service department (p. 35).
