Fail test:
The CX-1102 will flash "Wind Failure" then "Pg Up" in the bottom center of the display.
Check the following:
a. Control Output Unwind/Wind wiring to the drive
b. encoder input wiring
c. drive armature and power wiring
d. is the drive enabled
e. is this a Unipolar Reverse setup - check the PLC program and verify the correct
connection to the drives reversing input.
Press the "Page Up" key to restart this step (Wind Polarity Test).
Pass test:
The CX-1102 will flash "Wind PASS" then "KeyLk" in the bottom center of the display.
Setup State {MP-59} will equal 5.
The CX-1102 will change the WindEncPty {CP-269} to match the control output signal based on the
recorded information. For unipolar drives, WindCOPolarity {CP-287} may also have been changed
based on the recorded information.
If the wind axis is NOT under CX-1102 control:
1) Rotate the wind roll in the forward direction, then in the reverse direction.
2) Observe the value in WindEncRPM {MP-12} for a sign change. If the sign does not change then check the
encoder input wiring.
Pass test:
The CX-1102 will flash "Wind PASS" then "KeyLk" in the bottom center of the display.
Setup State {MP-59} will equal 5.
Unwind Polarity Test:
1) Momentarily close the KeyLk input to initiate the test.
2) The CX-1102 will test the unwind axis.
For Bipolar and Unipolar Reversing Drives: The CX-1102 will ramp the Control Output command
positive, and back to zero, then negative, and back to zero.
For Unipolar Drives: The CX-1102 will ramp the Control Output command positive, and back to
zero. If no feedback occurs, it will negate UwndCOPolarity {CP-282}, then ramp the Control Output
command positive, and back to zero.
Fail test:
The CX-1102 will flash "Uwnd Failure" then "Pg Up" in the bottom center of the display.
Check the following:
a. Control Output Unwind wiring to the drive
b. encoder input wiring
c. drive armature and power wiring
d. is the drive enabled
e. is this a Unipolar Reverse setup - check the PLC program and verify the correct
connection to the drives reversing input.
Press the "Page Up" key to restart this step (Wind Polarity Test).
Pass test:
The CX-1102 will flash "Unwind PASS" then "Pg Down" in the bottom center of the display.
Setup State {MP-59} will equal 6.
