■ Guideline for the setting
Set <UL: Upper limit frequency> to a value which is ten times or less the values of <vL: Base
frequency 1>.
If the output frequency is exceeding to 10 times of <vL>, the "A-05" alarm will appear, and the value
of the output frequency will be limited to a value which is 10 times the value of <vL: Base frequency
1>.
The same holds for Base frequency 2 - 4. (Refer to [6. 4].)
