Backlash Compensation
When using a rotary encoder with a lead screw, a change in direction
of the table might cause an error in the displayed position due to
clearances within the lead screw assembly. This clearance is referred
to as backlash. This error can be compensated for by inputting the
amount of backlash within the lead screw into the Backlash
Compensation feature. See screen to the right.
If the rotary encoder is ahead of the table (displayed value is greater
than the table’s true position), this is called positive backlash, and the
value entered should be the positive value of the amount of error.
No Backlash Compensation is 0.000.
Counter Settings
The COUNTER SETTINGS feature is the parameter where the
operator defines the user application for the readout. The choices are
for milling, or turning applications.
A FACTORY DEFAULT soft key appears in the Counter Settings
choice of options. When pressed, the configuration parameters
(based on either mill, or turn) will be reset to factory defaults. A
responses of YES to set parameters to factory default settings, or NO
to cancel, and return to previous menu screen is required.
The Number of Axes field sets the number of axes needed. A 1,
2, OR 3 soft key will appear to choose between either 1, 2 or 3 axes.
