5.1.3 Characteristic

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.

he 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.

he characteristic points X1 and X2 are stated as percenta

es, as the analo

input can

be switched as a current or voltage input via switch S3.

566 Characteristic point X2 -100.00 % 100.00 % 98.00 %

567 Characteristic point Y2 -100.00 % 100.00 % 100.00 %

The coordinates of the characteristic points are related as a percenta

e to the analo

signal, with 10 V or 20 mA, and the parameter Maximum Frequency 419 or parame-

ter

Maximum reference percentage 519. The chan

e of direction of rotation can be

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-poin

form of the straight-line equation. The speed Y of the drive mechanism is controlled

according to the analog control signal X.

Attention!

Monitoring of the analog input signal via the parameter

Behavior 563 demands a check of the characteristic parameters. Sensible

use is only possible if the

Characteristic point X1 564 is in the positive

range.
