P-56x Nanopositioners
NOTICE
Reduced lifetime of the piezo actuator 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 actuator.
When the P-56x is not used but the controller remains switched on to ensure
temperature stability, discharge the P-56x (p. 30).
NOTICE
Operating voltages that are too high or incorrectly connected!
Operating voltages that are too high or incorrectly connected can cause damage to
the P-56x.
Only operate the P-56x with controllers/drivers and original accessories from PI.
Do
not
exceed the operating voltage range (p. 40) for which the P-56x is
specified.
Only operate the P-56x when the operating voltage is properly connected; see
"Pin Assignment" (p. 44).
NOTICE
Uncontrolled oscillation!
Oscillations can cause irreparable damage to the stage. 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 stage 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 stage.
INFORMATION
The arrows in the figures (see "Dimensions", p. 42) show the positive direction of
motion.
