Excessively high or wrongly connected operat-
ing voltages can cause damage to the position-
er.
X
Use compatible electronics and cables only.
X
Pay attention to the operating voltage
range of the positioner (see manual).
A high operating frequency in step mode and
continuous use of a short travel range can
cause considerable wear on the positioner.
X
If possible, reduce the operating frequency
and duration.
X
Stop the motion immediately if an electron-
ics malfunction occurs.
X
If possible, select another part of the travel
range as working range at regular intervals.
Handling Vacuum-Compatible Products
If the positioner is vacuum-compatible, atten-
tion must be paid to cleanliness.
X
Touch the stage only with powder-free
gloves.
X
If necessary, wipe the positioner clean.
Mounting the Positioner
and Connecting to
the Protective Earth
Conductor
CAUTION!
If there is no protective earth conductor,
there is a danger of minor injuries from
electric shock.
X
Operate the stage only with a
properly connected protective earth
conductor.
X
Pay attention to the applicable stan-
dards for attaching the protective
earth conductor .
Suitable Protective Earth Conductor
▪
▪
Cross section of the protective earth con-
ductor ≥0.75 mm².
Mounting the Positioner
1. Use sufficiently conductive screws in all
mounting holes to fix the stage to an under-
lying surface.
2. Tighten the mounting screws with at least 3
turns (see manual for torque).
3. Secure the screws against unintentional
loosening, e.g., with locking paint
4. Make sure that the contact resistance is
<0.1 Ω at 25 A at all protective earth con-
ductor connections.
If ground loops occur, contact the PI cus-
tomer service department.
5. Hold the motion platform firmly or secure it
against moving while mounting the load.
6. Fix the load to the mounting holes provid-
ed.
