Functions with parentheses will produce different values depending on which of the following is contained in their
parentheses.
• Total: Total value (The total value of all harmonic components from the minimum order to N.
*
For information
about how the value is determined, see appendix 1 in the getting started guide, IM WT1801-03EN.)
• 0(DC): DC value
• 1:
Fundamental harmonic value
• k:
The value of any order from 2 to N.
*
* N is the maximum measurable order. The maximum measurable harmonic order is the smallest of the three
orders listed below.
• The specified maximum measurable harmonic order
• The value determined automatically according to the PLL source frequency (see section 6.4 in the getting
started guide, IM WT1801-03EN)
• When the data update interval is 50 ms, the maximum measurable harmonic order is 100.
