• The position feedback is to be measured in thousandths of inches, so 1000
position units per inch is entered in the Desired Position Units field.
• The transducer gradient information in the Transducer field is found on
the transducer.
• To set the offset, the following steps are performed
− Retract the cylinder all the way. This can be done by issuing anOpen
Loop (O) command with a small amount of drive.
− When the cylinder is all the way retracted, the transducer shows 1024
counts in this example.
− If this is the desired zero point, click the button in the Offset field and
it automatically enters 1024 into the counts field.
− …increasing counts is selected in the Increasing counts equal…
field.
• Set the desired extend and retract limits to 0.100 and 52 inches. This
system can extend 52.700 inches, but it is undesirable to ever reach either
end.

Now the system is set up and ready to tune for position. The procedure in
Tuning a Position Axis is followed:

see if the cylinder goes in the right direction.
• If the cylinder moves in the wrong direction, the wiring to the drive may be
swapped, or Reverse Drive mode can be selected in the Config word.
