Configuring the display
In the DISPLAY CONFIGURATION form you determine the display
resolution for the different encoders.
 In the INSTALLATION SETUP menu, select DISPLAY
CONFIGURATION.
 If you have configured the ND for two axes in the APPLICATION
field under COUNTER SETTINGS, a list of the possible encoder
inputs, labelled INPUT X1 and X2, appears.

Scroll to the input you want to configure and press ENTER.
Linear encoder
 Press the COARSER or FINER soft key to select the display
resolution for the axis display in the DISPL. RESOLUTION X1 or
X2 field.
Rotary encoder
 Press the COARSER or FINER soft key to select the display
resolution for the axis display in the DISPL. RESOLUTION X1 or
X2 field.
 In the ANGLE DISPLAY field, press the ANGLE soft key to choose
between the three following angle formats:
 +/– 180 DEGREES
 360 DEGREES
 +/– INFINITE
Analog sensor for compensation
 Press the COARSER or FINER soft key to select the display
resolution for the measured value in the DISPL. RESOLUTION X1 or
X2 field. The minimum resolution depends on the assignment of the
measured values to the voltage values. The ND subdivides the input
voltage range of ±10 V 4096-fold, i.e. in steps of 5 mV.

The selectable display resolution depends on the signal
period. The smallest selectable display resolution
corresponds to the rounded-off value calculated from
dividing the signal period by 4096. For linear encoders,
resolutions from 0.5 mm to 0.001 µm are possible, and for
rotary encoders from 0.5° to 0.000001° (00°00'00.1").
If two axes are coupled, the finer of the two display
resolutions will be used.
