P-62x Positioners
NOTICE
Decreased lifetime due to permanently high voltage!
Applying a continuous high static voltage to piezo actuators reduces the lifetime of the piezo
ceramic.
When the P-62x is not used but the electronics remain switched on to ensure temperature
stability, discharge the P-62x (p. 33).
NOTICE
Shortened lifetime of the flexure guides in dynamic operation!
Dynamic operation and scanning applications can shorten the lifetime of flexure guides
significantly when using the maximum travel range in open-loop operation.
Avoid full load in open loop during dynamic operation and in scan applications. If your
application requires a corresponding operating mode, contact our customer service
department (p. 39).
NOTICE
Uncontrolled oscillation!
Oscillation can cause irreparable damage to the P-62x. Oscillation is indicated by a humming
noise and can be caused by the following:
A change in the load and/or dynamics requires the servo control parameters to be
adjusted.
The P-62x is operated near to its resonant frequency.
If you notice oscillation:
In closed-loop operation, switch off the servo mode immediately.
In open-loop operation, stop the P-62x immediately.
INFORMATION
The P-62x's direction of motion is indicated in the product view (p. 12).
INFORMATION
Systems are calibrated at the factory to achieve optimum positioning accuracy. Replacing the
system components can lead to a reduction of position accuracy when positioners are used
with an ID-chip that does not contain calibration data or when LEMO plug connectors are used.
When connecting the positioner, pay attention to the assignment of the motion axes to the
controller channels, which is specified on the calibration label of the controller.
If position accuracy is reduced after replacing the P-62x or the controller:
Perform a recalibration of the axis displacement (see controller manual) or contact our
customer service department (p. 39).
