p Misc screen
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.
 External axis-zero enable for X, Y and Z/Q axes. Allows axes to be
zeroed remotely from encoder zero buttons.
 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.
 Screen saver minutes: The period of time that the DRO can be idle
before going into activating the screen saver.
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 X, Y or Z/Q External 0 choice field and then press the
Yes
or No soft key to enable or disable external axis zeroing by the
remote encoder.
 Highlight the Slew Limit data field and enter the slew rate limit
(increments of resolution per second). For example, at an encoder
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.
 Highlight the Scr Saver Min data field and enter the number of
minutes the DRO is idle before the screen saver is activated.
 Press the FINISH key to save parameters and return to the Setup
menu.
