Parameter Descriptions
6-62 Terminal X30/8 Max. Scale
Range: Function:
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 x 100 %
i . e . 10 mA :
6-63 Terminal X30/8 Bus Control
Range: Function:
0 % [0 - 100 %] Holds the level of output X30/8 if
*
controlled by bus.
6-64 Terminal X30/8 Output Timeout Preset
Range: Function:
0 % [0 - 100 %] Holds the preset level of output
*
X30/8.
If there is a fieldbus timeout and a
timeout function is selected in
parameter 6-60 Terminal X30/8
Output, the output is preset to this
level.
3.7.8 6-7* Analog Output 3 MCB 113
Parameters for configuring the scaling and limits for analog
output 3, terminals X45/1, and X45/2. Analog outputs are
current outputs: 0/4–20 mA. Resolution on analog output
is 11 bit.
6-70 Terminal X45/1 Output
Option: Function:
Select the function of terminal
X45/1 as an analog current output.
[0] No operation When no signal on the analog
output is present.

[103] Motor Current The value is taken from
parameter 16-37 Inv. Max. Current.
The inverter maximum current
(160% current) is equal to 20 mA.
Example: Inverter normal current
(11 kW) = 24 A. 160% = 38.4 A.
