Establishing a repeatable machine zero
If your ND 1200 was configured to establish a machine zero upon
power-up, a message will be displayed asking you to cross reference
marks or enter hard-stop axis reference positions. The machine zero is
used by the ND 1200 to apply error correction data as measurements
are performed. To establish a repeatable machine zero you must
either:
U
Move the stage to have encoder reference mark crossings
recognized on each axis
or
U move the stage to the hard-stop reference position and press
ENTER on each axis when no encoder reference marks are present.
Switching off the ND 1200
Switch the ND 1200 off. The parameter settings,
error compensation tables and recorded programs
that have been saved during operation will be
retained in memory.
If the requirement to cross reference marks is bypassed
by pressing the CANCEL soft key, error correction data
that might be stored in your ND 1200
will not be applied .
Your ND 1200 might also have been configured to retain
measurement results across power cycles
