CONTREX CX-1102 - Manual (Page 16)

Page 14
The CX-1102 will change the UwndEncPty {CP-264} to match the control output signal based on
the recorded information. For unipolar drives, UwndCOPolarity {CP-282} may also have been
changed based on the recorded information.
If the unwind axis is NOT under CX-1102 control or is Unipolar Brake:
1) Rotate the unwind roll in the forward direction, then in the reverse direction.
2) Observe the value in UwndEncRPM {MP-02} for a sign change. If the sign does not change then check the
encoder input wiring.
Pass test:
The CX-1102 will flash "Uwnd PASS" then "Pg Down" in the bottom center of the display.
Setup State {MP-59} will equal 6.
Press the “Page Down” key to proceed to the next step.
