Features of set-value 1

An analog entry of set-value 1 is possible via input X1/terminal 8,
otherwise it is entered via the keypad or the LECOM interfaces.
This depends on the selected operating mode (C001). The
configuration determines whether the input is unipolar, bipolar, or
independently of the operating mode, a digital frequency input.

With terminal control you can read set-value 1 under code C046.
Under code C172 you can select whether the set-value is to be
displayed in per cent (related to f

dmax

) or as absolute value.

With control via keypad or LECOM you can enter under C172 how
you want to enter set-value 1, in per cent related to f

dmax

or as

absolute value in Hz.
