The Misc screen encoder configuration fields include:
 Auto DRO counts: The number of least significant DRO counts
required to refresh the DRO with new axis values.
 Slew limit for the axes: High input slew rates resulting from rapid
input encoder motion can result in erroneous measurements.
Erroneous measurements are avoided by displaying encoder error
warnings when encoder values change at very high rates.
To configure encoder settings in the Misc screen:
 Press MENU>SETUP to display the setup menu and then highlight
the Misc menu item.
 Highlight the Auto DRO Cnts data field and enter the number of
DRO counts (axis motion) in the least significant digit position
required to automatically refresh the DRO axis values.
 Highlight the Slew Limit data field and enter the slew rate limit
(increments of resolution per second). For example, at a channel
resolution of 0.001 mm, a slew rate limit of 50,000 will result in
warning messages at encoder motion rates higher than 50 mm per
second.
 Press the FINISH key to save parameters and return to the setup
menu.
