84 EM-ABS-01 for ACU 03/12
8 Control inputs and outputs
8.1 Analog input EM S1INA
8.1.1 General
The analog input of the EM-ABS-01 extension module can be used as a volta
g
e input.
Parameterization of the input signal is done via the definition of a linear characteristic
and assignment as
− Reference value source
(selectable via parameter 󳮁
Reference frequency source 475),
− Reference percentage source
(selectable via parameter 󳮁
Reference percentage source 476),
− Actual percentage source
(selectable via parameter 󳮁
Actual percentage source 478, in configuration x11)
or
− limit value sources
(can be selected via the parameters 734 … 737).
8.1.2 Characteristic
Mapping of the analog input signal onto a reference frequency value or a reference
percentage value is possible for various requirements. Parameterization is to be done
via two points of the linear characteristic of the reference value channel.
T
he characteristic point 1, with the coordinates X1 and Y1, and the characteristic poin
t
2, with the coordinates X2 and Y2, can be set in four parameters.
Points X1 and X2 are stated in per cent, as the analo
g
input can be switched as a
current or voltage input via switch S3.

The definition of the analog input characteristic can be calculated via the two-point
form of the line equation. The speed Y of the drive is controlled ac-cording to the ana-
log control signal X.
