Parameter Descriptions
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
Same options and functions as parameter 6-50 Terminal 42
Output.
6-61 Terminal X30/8 Min. Scale
Range: Function:
0 % [0 - 200 %] Scales the minimum output of the
*
selected analog signal on terminal
X30/8. Scale the minimum value as
a percentage of the maximum
signal value. For example, enter the
value 25% if the output should be
0 mA at 25% of the maximum
output value. The value can never
exceed the corresponding setting in
parameter 6-62 Terminal X30/8 Max.
Scale if the value is below 100%.
This parameter is active when VLT
General Purpose I/O MCB 101 is
mounted in the frequency
converter.
6-62 Terminal X30/8 Max. Scale
Range: Function:
100 % [0 - 200 %] Scales the maximum output of the
*
selected analog signal on terminal
X30/8. Scale the value to the
required maximum value of the
current signal output. Scale the
output to give a lower current than
20 mA at full scale, or 20 mA at an
output below 100% of the
maximum signal value. If 20 mA is
the required output current at a
value between 0–100% of the full-
scale output, program the
percentage value in the parameter,
that is 50%=20 mA. If a current 4–
20 mA is required at maximum
output (100%), calculate the
percentage value as follows:
20 mA/desired maximum current × 100 %
i . e . 10 mA:
6-63 Terminal X30/8 Output Bus Control
Range: Function:
0 % [0 - 100 %] Contains the value to apply to the
*
output terminal when it is
configured as bus-controlled.

8-02 Control Source
Select the source of the control word: 1 of 2 serial interfaces, or
4 installed options. During initial power-up, the frequency
converter automatically sets this parameter to [3] Option A if it
detects a valid fieldbus option installed in slot A. If the option is
removed, the frequency converter detects a change in the
configuration, sets parameter 8-02 Control Source back to default
setting [1] FC Port, and the frequency converter trips. If an option
is installed after initial power-up, the setting of
parameter 8-02 Control Source does not change but the
frequency converter trips and shows alarm 67, Option Changed.
Option: Function:
