Problem
Possible Causes
Solution
Stage does not
move
Cable is not
connected correctly
Check the cable connections.
Stage or stage cable
is defective
Replace the defective stage with a suitable stage and
test the new combination.
Control signal
exceeds the
permissible range
Check the control input voltage (
Control In
BNC socket)
and the setting of the
DC Offset
potentiometer.
If you generate the control input voltage with a data
acquisition board using the LabVIEW analog drivers:
Check that the analog drivers and the data acquisition
board are working correctly.
E-836.1G voltage
output is deactivated
When the internal temperature reaches ≥85° C the E-
836.1G voltage output is deactivated and the stage stops
moving. When the internal temperature then drops to 75° C,
the voltage output is switched on again automatically.
Ensure sufficient ventilation at the place of installation.
Reduce the frequency and/or the amplitude and/or the
output duration of the control input voltage (
Control In
BNC socket).
If the problem that occurred with your system is not listed in the table above or cannot
be solved as described, contact our customer service department (p. 25).
