4.
Find the encoder marker for the master servo. First select the master
axis name from the softkeys so that you are looking at data for the
master axis. Then slowly jog the split axis (using the axis name
defined in AMP as the master axis) while watching the lower right
hand corner of the axis monitor screen. Jog the axis only until
“marker found” is displayed.
5.
Find the encoder marker for the slave servo. This time select the
slave axis name from the softkeys so that you are looking at data for
the slave axis. Then slowly jog the split axis (still using the axis
name defined in AMP as the master axis) while watching the lower
right hand corner of the axis monitor screen. Again, jog the axis only
until “marker found” is displayed.
6.
Physically secure the axis so that it cannot be moved. Use weights,
clamps, or whatever is necessary to prevent axis skew from occurring
while you work on the encoders.
7.
Place the control in E-Stop and verify that power to the drives is
turned off.
