Parameter Settings – F 20
F 20 allows you to set up encoder parameters and axis display resolutions. The following
section describes two different types of resolution:
q Encoder Resolution the resolution of the measurement, an encoder parameter.
q Display Resolution the resolution of displayed values.
You can vary the resolution of the values displayed in the linear axis displays for both
INCH and MM Mode. For a rotary axis, you can set up the display resolution for degrees
in both decimal and minutes/seconds format. You can set the display resolution
individually for each axis.
F 20 allows you to enter parameters for the encoders used for feedback. These can be
set up individually for each axis. Your DRO will support three different types of encoders:
q Metric Linear Encoders (encoders with grating pitch measured in microns, µm)
q Inch-Based Linear Encoders (encoders with grating pitch measured in inches)
q Rotary Encoders
All modern linear encoders are of the Metric type.
NOTE: F 20 is also used to specify the parameters of the spindle encoder used for
feedback for Spindle Speed Display (SSD). See Parameter Setting for SSD (2-
Axis and 3-Axis With SSD Option Only).
Setting Up Encoder Parameters
To enter encoder and axis display parameter settings:
1. Press to select the feature.
The DRO displays the following in the message window:
2. Press the desired axis key(s) to select the axes.
