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.

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.

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.

Place the control in E-Stop and verify that power to the drives is

turned off.
