Operating Instructions ACU
Ind. volume flow control factor
In Operation Modes 1,2,3 and 5 the output frequency is shifted on the y-axis by the Minimum
Frequency 418. The technology controller output value in percent thus is:
0 % = Minimum Frequency 418
100 % = Maximum Frequency 419
The parameterization of the technology controller in the individual data sets enables
an adaptation to various operating points of the application with the data set change-
over via control contacts.
The technology controller works in clockwise motor sense of rotation. The sense of
rotation can be reversed via parameter Change Sense of Rotation 1199. See Chapter
11.2.8 "11.2.8".
