P-5x7/P-5x8 Positioners
NOTICE
Operating voltage too high or incorrectly connected!
Operating voltages that are too high or incorrectly connected can cause damage to the
P-5x7/P-5x8.
Operate the P-5x7/P-5x8 only with controllers/drivers and original accessories from PI.
Do
not
exceed the operating voltage range (p. 40) specified for the P-5x7/P-5x8.
Operate the P-5x7/P-5x8 only when the operating voltage is properly connected; refer to
"Pin Assignment" (p. 45).
NOTICE
Uncontrolled oscillation!
Oscillation can cause irreparable damage to the P-5x7/P-5x8. 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-5x7/P-5x8 is operated close to its resonant frequency, or with too high operating
frequency.
If you notice oscillation:
In closed-loop operation, switch off the servo mode immediately.
In open-loop operation, stop the P-5x7/P-5x8 immediately.
INFORMATION
The positive direction of motion is specified in the dimensional drawing (p. 42) by arrows.
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 (p. 13) 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-5x7/P-5x8 or the controller:
Recalibrate the axis displacement (refer to the controller manual) or contact our customer
service department (p. 35).
INFORMATION
Sound and vibration (e.g., footfall, knocks) can be transmitted to the P-5x7/P-5x8 and can
affect its performance with regard to position stability.
Avoid sound and vibration while the P-5x7/P-5x8 is being operated.
