Parameter Descriptions
3.8.6 6-5* Analog Output 1
Parameters for configuring the scaling and limits for
analog output 1, i.e. Terminal 42. Analog outputs are
current outputs: 0/4 to 20 mA. Common terminal (terminal
39) is the same terminal and has the same electrical
potential for analog common and digital common
connection. Resolution on analog output is 12 bit.
5-17 Terminal X30/3 Digital Input
Option: Function:
[0] No This parameter is active when option module

operation MCB 101 is installed in the frequency
converter. Functions are described under 5-1*
Digital Inputs
6-51 Terminal 42 Output Min Scale
Range: Function:
0 % [0 - Scale for the minimum output (0 or 4 mA) of the
*
200 %] analog signal at terminal 42.
Set the value to be the percentage of the full
range of the variable selected in 6-50 Terminal 42
Output.
6-52 Terminal 42 Output Max Scale
Range: Function:
100 [0 - Scale the maximum output of the selected analog
% 200 signal at terminal 42. Set the value to the
*
%] maximum value of the current signal output. Scale
the output to give a current lower than 20 mA at
full scale; or 20 mA at an output below 100% of
the maximum signal value. If 20 mA is the desired
output current at a value between 0 - 100% of
the full-scale output, programme the percentage
value in the parameter, i.e. 50% = 20 mA. If a
current between 4 and 20 mA is desired at
maximum output (100%), calculate the percentage
value as follows:
20 mA / desired maximum current x 100 %

6-53 Terminal 42 Output Bus Control
Range: Function:
0 % [0 - 100 %] Holds the level of Output 42 if controlled by

bus.
6-54 Terminal 42 Output Timeout Preset
Range: Function:
0 % [0 - 100 Holds the preset level of Output 42.

is selected in 6-50 Terminal 42 Output, the
output is preset to this level.

3.8.7 6-6* Analog Output 2 MCB 101
Analog outputs are current outputs: 0/4 - 20 mA. Common
terminal (terminal X30/8) is the same terminal and
electrical potential for analog common connection.
Resolution on analog output is 12 bit.
6-60 Terminal X30/8 Output
Option: Function:
Select the function of Terminal X30/8 as an
analog current output. Depending on the
selection the output is either a 0-20 mA or
4-20 mA output. The current value can be
read out in LCP in 16-65 Analog Output 42
