NOTICE
Operating voltage too high or incorrectly connected!
Operating voltages that are too high or incorrectly connected can cause damage to the
NanoCube® nanopositioner.
Only operate NanoCube® nanopositioners with controllers/drivers and original accessories
from PI.
Do
not
exceed the operating voltage range for which the NanoCube® nanopositioner is
specified.
Only operate the NanoCube® nanopositioner when the operating voltage (power
connector) is properly connected.
NOTICE
Destruction of the piezo actuators by electric flashovers!
The use of the NanoCube® nanopositioner in environments that increase the electrical
conductivity can lead to the destruction of the piezo actuator by electric flashovers. Electric
flashovers can be caused by moisture, high humidity, liquids and conductive materials such as
metal dust. In addition, electric flashovers can also occur in certain air pressure ranges due to
the increased conductivity of the air.
Avoid operating the NanoCube® nanopositioner in environments that can increase the
electric conductivity.
Only operate the NanoCube® nanopositioner within the permissible ambient conditions
and classifications (p. 34).
NOTICE
Reduced lifetime of the piezo actuators due to permanently high voltage!
The permanent application of a high static voltage to piezo actuators leads to a considerable
reduction in the lifetime of the piezo ceramics of the NanoCube® nanopositioner.
When the NanoCube® nanopositioner is not used but the controller remains switched on
to ensure temperature stability, discharge the NanoCube® nanopositioner (p. 31).
NOTICE
Uncontrolled oscillation!
Oscillations can cause irreparable damage to the NanoCube® nanopositioner. Oscillations are
indicated by a humming and can result from the following causes:
A change in the load and/or dynamics requires the servo-control parameters to be
adjusted.
The NanoCube® nanopositioner is operated near its resonant frequency.
If you notice oscillations:
In closed-loop operation, immediately switch off the servo mode.
In open-loop operation, immediately stop the NanoCube® nanopositioner.
