Specifying encoder parameters
Use the encoder screen to specify encoder resolu-
tion, units of measure, count direction and refer-
ence mark type.
Click the Tools/Options/Encoders menu item to
display the Encoders screen.
Specifying encoder resolu-
tion
Enter the resolution specification of the encoders
used with your system into the X, Y and Z Resolu-
tion fields.
Specifying encoder unit of
measure
Check the mm box for metric encoders, or clear the mm box for encoder output values in inches.
Specifying encoder count direction
Check or clear the reverse boxes to achieve the desired DRO count directions.
Specifying encoder reference marks
Highlight the desired reference mark type in the drop-down lists,
and then clear the TTL Ref box for analog reference marks.
Reference offsets
The Reference offsets fields are used by OEM setup personnel and qualified service technicians to move
the location of the system’s machine zero.
CAUTION
The machine zero location must be undisturbed to ensure correct operation and ac-
curate error correction. Do not change to reference offsets values.
