If UwndCO Mode {CP-280} is set to Unipolar, this test Fails.
If UwndCO Mode {CP-280} is set to Bipolar or Unipolar Reversing, UwndCOPolarity {CP-282}
and UwndEncPlrty {CP-264} are changed, and a positive command is issued to the Unwind axis
again for forward rotation (maximum of 2X number of rotations). The CX-1102 will montior the
Dancer content for movement toward the Full position.
If the Dancer moves to its Full position, both rolls are stopped, and the test Passes.
Fail test:
Check the following:
a. is web threaded into machine
b. drive armature and power wiring
c. is the drive enabled
d. gear reduction is correct
Press the "Page Up" key to restart this step (Unwind Direction Test).
Pass test:
The CX-1102 will flash "Uwnd PASS" then "Setup Done" in the bottom center of the display.
Setup State {MP-59} will equal 10.
Proceed to End of Unwind Direction Test.
If the unwind axis is NOT under CX-1102 control, if App Select {CP-202} is a 4 (DT Wind only):
1) Momentarily close the KeyLk input. The CX-1102 will montior the Unwind feedback and the Dancer
content for movement from approximately 3/4 of Full to Full.
2) Rotate the Unwind roll in the forward direction.
3) When the dancer moves, the CX-1102 will change the UwndEncPlrty {CP-264} value so UwndRollRPM
{MP-03} is a positive (no ‘-‘ sign) signal for forward rotation of the Unwind roll and the test Passes.
Fail test:
Check the following:
a. is web threaded into machine
b. drive armature and power wiring
c. is the drive enabled
Press the "Page Up" key to restart this step (Unwind Direction Test).
Pass test:
The CX-1102 will flash "Uwnd PASS" then "Setup Done" in the bottom center of the display.
Setup State {MP-59} will equal 10.
End of Unwind Direction Test
Open the "Setup" input, the CX-1102 control is in F-Stop and will automatically display the "Main Menu" screen.
Remove any temporary terminal wiring.
