DANGER
Motion will occur in the calibration procedure.
It is possible that sudden/violent motion could
result and cause damage or personal injury.
Make sure that the motor is secured in place.
Take all possible precautions to ensure your
safety.
SYSTEM SETUP PROCEDURE
This procedure is a series of steps designed to verify the motor/drive/encoder wiring and polarity, calibrate the dancer
and setup some of the basic parameters necessary for proper operation of the CX-1102.
Before you begin this procedure, the motor and drive must be wired and configured in accordance with the manufacturer’s
instructions. Refer to your drive manual to assist you in making the following drive adjustments:
•
Set the acceleration and deceleration times to their fastest settings.
•
Set the IR compensation to its minimum setting.
•
Set the Integral compensation to its minimum setting.
The CX-1102 must be configured and installed in accordance with the installation procedures indicated in the Installa-
tion section of the CX-1102 Technical Reference Manual and the CX-1102, including its PLC, will be programmed as
factory default.
NOTE: The Wind Under Wrap input MUST be shorted to common if the wind axle will have web material fed onto
the roll from the bottom rather than the top of the roll. The Unwind Under Wrap input MUST be shorted to
common if the unwind axle will have web material fed off of the roll from the bottom rather than the top of
the roll.
NOTE: The Menu and Status keys will be disabled during the setup procedure. This is done in order to simplify the
automatically displayed screen sequence used while performing the setup procedure.
NOTE: Unipolar drives should not be used unless there is a large gear reduction between the motor and the roll,
because the unipolar drive can not provide reverse torque to hold the roll in position.
NOTE: The F-stop, Unload and H-Stop inputs are monitored during "Setup State". If any of these inputs are
opened during a test the CX-1102 will immediately zero the Control Outputs and display "Failure" for the
test in progress.
