Analog input EM S1INA

8.1.1 General

The analog input of the EM-ABS-01 extension module can be used as a voltage 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 percentage source
(selectable via parameter
−
Actual percentage source
(selectable via parameter
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.
The characteristic point 1, with the coordinates X1 and Y1, and the characteristic point
2, with the coordinates X2 and Y2, can be set in four parameters.
Points X1 and X2 are stated in per cent, as the analog input can be switched as a
current or voltage input via switch S3.

frequency inverter and/or by selection of the points.
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.
