a servo axis, feedback is momentarily disabled and then
re-enabled ( if the error checking features do not detect

an error) in the motion controller. If the axis has stored
energy or the ability to move during the time feedback is
disabled, you have to apply a breaking mechanism to the
axis before you execute the procedure.
Aligning Absolute Encoder
Once the hardware is wired and the configuration steps have been
taken, it is important to align the Absolute Encoder. The alignment
process aligns the absolute device to the zero position of the axis, and
updates both the working and power-up home position values. It also
changes the Position setting in the Homing page of the Configure Axis
Use dialog box. This is done from the Hookups section of the
Configure Axis Use screen in GML Commander.
To align the devices:
1. Make sure all external components are connected.
2. Make sure All Configured Axis Use information is entered. (Refer
to previous steps in this chapter.)
3. Download the Configured Axis information.
4. Select the Hookups tab from the Configure Axis Use screen.
5. Click on the Align Absolute Device button.
6. In response to the Commander message box, move the axis to
its minimum travel position and click on OK.
7. The alignment procedure runs.
For more information about alignment, see the GML Commander User
Manual (publication number GMLC-5.1), the "Configuring Your Axis"
chapter, "Verifying Hookups" section and the GML Commander
Reference Manual (publication number GMLC-5.2), the "Configuring
Your Axis" chapter, "Verifying Hookups" section.
