Step 5 - Signal Polarity Test
The CX-1102 will display System Setup Signal Polarity\Page 5. Setup State {MP-59} will equal 4.
Setup State {MP-59}
WindCO Volts {MP-37}
WindCOPolarity {CP-287}
WindEncRPM {MP-12}
WindEncPty {CP-269}
UwndCO Volts {MP-27}
UwndCOPolarity {CP-282}
UwndEncRPM {MP-02}
UwndEncPty {CP-264}
SigPolarity {MP-71}
NOTE: The Help key accesses the Help screen and gives you a brief description of the parameter or
subject that is highlighted (active) on the screen. Press the Help key again to return to the previous screen.
This test aligns the Control Output polarity and the Encoder polarity, so a positive Control Output command causes
positive Encoder feedback.
If the wind and/or unwind axis is under CX-1102 control:
NOTE: This step will make use of "Direct" mode and ramps.
NOTE: The Keypad will be disabled while this test is moving the wind/unwind axis.
WARNING
Prepare the machine for motion.
Alert everyone present.
The CX-1102 will flash "KeyLk" in the bottom center of the display.
Wind Polarity Test:
1) Momentarily close the KeyLk input to initiate the test.
2) The CX-1102 will test the wind 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 WindCOPolarity {CP-287}, then ramp the Control Output
command positive, and back to zero.
