14.2 Congure analog inputs
14.2.1
Analog input 1
Sengs for analog input 1.
Details
The analog input 1 can be used as setpoint source.
The following sengs are possible for the analog input:
•
Denion of the input range
①
•
Filt
er me for low-pass lters
②
•
Denion of the seng range (min/max range)
③
•
Dead band f
or eliminang the smallest signal levels
④
•
Manual I/O c

Denion of the input range
The analog input can be congured as voltage or current input. Internally, the signal is always
converted to a value in percent.
Denion of the seng range
The seng range results from the set min and max value for the respecve mode.
Manual I/O control
The analog input can be overridden manually. Aer the funcon is acvated, the actual values
are "frozen". Aerwards, each analog input can be overwrien manually.

an be minimised.
•
For an opmum lter eect, rst the noise frequency has to be deter-
mined. The me constant then has to be set so that it equals the
reciprocal value of the double frequency.
