axis in the JOG mode, for example, the drift has
exceeded the permissible value and drift compensation
must be
carried
out.

Operating the appropriate DRIFT COMP.
. . . .
results in the
automatic drift compensation of the desired axis.
DRIFT COMP.
Notes:
In the case of an excessive drift, a following error remains for the axis in question. After
the drift compensation has been executed, the following error
tends to zero.
The drift values are entered in the following NC-MDs:
NC-MD 2720
NC-MD
2721
NC-MD
2722
NC-MD
2723
1 st
axis
2nd
axis
3rd axis
4th axis
Drift values can also be entered manually in NC-MDs 2720
to
2723 (see Section
3.3.3).
Drift values
greater
than 500 can no longer be called drift. Alarm
1 60' is then given (drift
too
high).
