Correction Cause Problem
In/Out Positioner actual
travel distance does not
match value shown on
iControl screens.
(continued)
Incorrect encoder resolution
entered on in/out positioner
configuration screen.
NOTE: Encoder resolution can only be
entered or changed by a Nordson
representative.
Verify encoder resolution (number of pulses
output for one inch of travel) and enter that
value on the in/out positioner configuration
screen.
If the number is not know and cannot be
mechanically calculated, then a trial and error
method can be attempted. Perform this
procedure from the in/out positioner
configuration screen:
1. Manually move the in/out positioner to the
forward limit (zero position).
2. Reverse the in/out positioner slightly off
the limit, record the displayed position
value, and apply reference marks to the
in/out positioner and base.
3. Manually move the in/out positioner in
reverse, almost but not all the way to the
reverse limit (the greater the distance the
more accurate the calculated resolution
will be).
4. Use your reference marks to measure the
distance moved and compare the
measured distance to the displayed
position value.
5. The ratio of these two values is used to
calculate a new encoder resolution. If the
displayed position value is greater than the
measured distance, then increase the
encoder resolution. If the displayed
position value is less than the measure
value, then decrease the resolution.
Mechanical failure in
connection of in/out
positioner encoder to
machine motion.
Check the mechanical components and
connections linking the encoder rotation to the
movement of the in/out positioner.
