Parameters Setup Procedure - NL ERROR
select the FIND REF ( find ref mark )
select the Axis
Let's take X as an example
select the X axis
move the machine across the ref mark of the scale until the digits
display start run.
Please remember that to move the scale
towards the positive direction during finding REF mark.
after the display digits start run,
move the move to X = 0.000,
it is the ref mark position of the
scale.
2) Locate the CP. START position
The CP. START position is the absolute reference for the internal error compensation calculation, it is the
start point of the error curve, to make fast real time compensation calculation possible, the DRO assume
all internal error compensation calculation are only in positive direction. Therefore, the CP. START position
should be always located in the most negative position of the machine, so that all measured position
in the error curve are located in positive direction.
In the example below, we are using a step guage which have total measurement travel of 300mm
as our our measurement standard. The step pitch of the step guage is 25.000mm
Our maximum machine travel is 265mm. Therefore,
CP. PITCH = 25.000mm
CP. STEP = 265/25 = 10.6 steps, since steps must be in integer, then round up to = 10 steps.
