Commission an Axis Chapter 11
4. The axis moves on its own to test for feedback polarity and proper
wiring. To check for proper rotation direction, watch the axis.
The drive determines that the feedback device is working properly and
the test passed.
5. Click OK.
6. If your axis moved in a forward direction, click yes and you see that the
test result is Normal.
If the motor does not move in the forward direction, according to your
application the test result is inverted. When you accept test results the
Current shows inverted.
See the Polarity on page 235
.
If you are satisfied with the results, you can accept the test results.
The test can pass but give you results that you are not expecting. In this
case, you can have a wiring problem.
See the related drive documentation that is listed in the Additional
Resources on page 9.
7. Click Yes or No depending on whether the axis moved in the forward
direction for your application.
8. Click Accept Results, if the test ran successfully.
