Rang
setting
error
Parameter setting
falls outside the
allowed range.
•
Some parameter ranges are
determined by other inverter
parameters which could cause an out
of range warning when the
dependency parameter is adjusted.
For example: 02-00>02-01, 00-12<00-
13 or when 00-07 = 1, 00-05 is the
same with 00-06 or 20-16 <= 20-15.
•
Check parameter setting.
