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