CONTREX CX-1200 - Manual (Page 81)

4 - 6
WARNING
Prepare the machine for motion.
Alert everyone present.
This test checks the Control Output polarity and the Encoder polarity, so a positive Control Output command causes
positive Encoder feedback.
Forward:
1. Enter RUN Mode {CP 202} = Direct.
2. Enter Direct SPx {CP-201} = +2.0 volts.
3. Place the control into "Run".
Verify forward motor direction:
4. If motor is running in the forward direction , skip to step 6.
5. Rewire the motor leads for forward direction.
Verify forward sensor polarity:
6. If FI2 Hz {MP-03} is a positive number, skip to step 8.
7. Rewire the feedback sensor polarity.
8. Place the control into "F-Stop".
Reverse:
Enter a direct mode setpoint for the reverse direction:
9. If CO Mode {CP-270} = Unipolar, skip to step 16.
10. Enter Direct SPx {CP-201} = -2.0 volts.
11. Place the control into "Run".
Verify reverse motor direction:
12. If motor is running in the reverse direction , skip to step 14.
13. Rewire the motor leads for reverse direction, verify the motor drive is bipolar or unipolar reverseable and
then recheck forward direction by returning to step 1.
Verify reverse sensor polarity:
14. If FI2 Hz {MP-03} is a negitive number, skip to step 16.
15. Rewire the feedback sensor polarity, and then verify the sensor polarity in the forward direction by
returning to step 1.
16. Place the control into "F-Stop".
17. Enter Direct SPx {CP-201} = 0 volts
