1) Mode state
– Mode enabled or disabled.
2) Parameter
– maintained parameter (output current of Freq. Converter,
motor winding temperature, pump intake pressure).
3) Correlation
– correlation of frequency regulation at system output when parameter deviates
from target value (direct, inverse). In direct
correlation, if parameter exceeds target value then it will cause frequency
increasing and vice versa: decreasing will lead to decreasing.
In inverse correlation, if
parameter exceeds target value then it will cause frequency decreasing and vice
versa: decreasing will lead to increasing.
4) Maintained
value – maintained value of the parameter.
5) Period of
regulation – time interval in which regulator compares current value of
maintained value to target value and adjusts output frequency.
6) Proportional
coefficient – proportional component of control signal. If coefficient
equals to 1 and difference between current and target values of the maintained
parameter also equals to 1, then output frequency will be changed by 1 Hz.
7) Integral
coefficient – integral component of control signal. If coefficient equals
to 1 and difference between current and target values of the maintained parameter
equals to 1 during regulation period, then output frequency will be changed by
1 Hz.
8) Min
operating frequency – lower limit of FC output frequency which cannot be
below that.
9) Max
operating frequency – lower limit of FC output frequency which cannot be
exceeded.
