Problem Possible Cause Corrective Action
In/Out Positioner actual
travel distance does not
match value shown on
iControl 2 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 ro ation to the movement of the in/out positioner.
