3. Select EverTrack Test. The Setup Utility displays:
Encoder Resolution
Encoder Type
Starting Mark (N)
The following information is displayed as the test is in progress:
mm between marks
Current Mark (N)
4. To determine the Starting Mark, move the axis to the right-most end of
the EverTrack encoder (as you look at the encoder). Note that you
must move the axis so that the Current Mark display,
changes/transitions at least twice (about two inches). If you are within
2 inches of the right-most end of the encoder, move in the opposite
direction (left) a few inches, and then move back to the right-most end
of the encoder. The Current Mark display also shows the proper sign.
5. Once you have found the right-most mark, press F2 and select Save
Current Mark to store the Current Mark in the configuration file as the
Starting Mark entry.
– or –
Write down the Current Mark (sign included) and go the Setup Utility’s
Starting Mark choice and enter the information.
Detecting the Index Pulse (F3)
Refer to Figure 1, CNC Motion Setup/Testing Screen. When you press
IndexP (F3), the CNC displays a flashing “I” each time it detects an Index
Pulse. The flashing “I” replaces the axis name (X, Y, or Z) of the active
axis. The index pulse indicator (flashing “I”) for the spindle axis is
displayed on the RPM field. In the figure, an index pulse has been
detected on the X-axis. Refer to Figure 3, Index Pulse Indicator.
To detect an index pulse:
1. Move the active axis to check for the presence of an index pulse.
2. On systems with rotary encoders with index pulses, the index pulse
should be detected once per revolution.
3. On systems having linear scales, the index pulse should be detected
where the linear scale specifies location of the index pulse.
