3.4 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.
Code Parameter Meaning Acceptance
C172 -0- Set-value input in per cent [SH + PRG]
C046 -100%...+100% of the maximum
field frequency (C011) Display/Input of set-value 1
Code Parameter Meaning Acceptance
C172 -1- Absolute set-value input [SH + PRG]
C046 -480...+480Hz Display/Input of set-value 1
Absolute set-values which are higher than the maximum field
frequency, are internally limited to the maximum field frequency
(C011).
3.4.1 Set-value input with master current
For analog set-value input with master current, first change the
switch setting of S1/4 on the control board (see page 29). C034 is
used to determine the setting range.
Code Parameter Meaning Acceptance
C034 -0-
-1- Master current 0 to 20 mA
Master current 4 to 20 mA SH + PRG
