NOTE
3 If vibration occurs on an axis after automatic setting,
set bit 4 of parameter No. 1884 for the axis to 0. In a
very rare case, vibration may occur as a result of the
machine characteristics when bit 4 of parameter No.
1884 is set to 1.
4 If parameter No. 1518 is set to specify a lower feed-
forward coefficient limit in automatic adjustment, the
lower limit value is always used when a finish above a
certain level is specified. For this reason, values
such as a time constant after interpolation calculated
using the feed-forward coefficient become identical.
Thus, automatic adjustment can produce the same
results even though a different finish level is
specified. In such a case, set parameter No. 1518 to
0, then make another automatic adjustment.
