The analog input of the EM-RES-03 expansion module can optionally be configured as
a voltage or a current input. Parameterization of the input signal is done by the defini-
tion of a linear characteristic and assignment as a

6.1.2
The mapping of the analog input signals onto a frequency or percentage reference
value is possible for various demands. The parameterization is to be done via two
points of the linear characteristic of the reference 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.
The characteristic points X1 and X2 are stated as percentages, as the analog input can
be switched as a current or voltage input via switch S3.
The coordinates of the characteristic points are related as a percentage to the analog
signal, with 10 V or 20 mA, and the parameter
ter
done via the digital inputs of the frequency inverter and/or by selecting the character-
istic points.
The definition of the analog input characteristic can be calculated via the two-point
form of the straight-line equation. The speed Y of the drive mechanism is controlled
according to the analog control signal X.
