[0.00 -
200.00 %]
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, i.e., 0 mA (or 0 Hz) is
desired at 25% of the maximum output value
and 25% is programmed. The value can never
be higher than the corresponding setting in
6-62 Terminal X30/8 Max. Scale if value is below
100%.
This parameter is active when option module
MCB 101 is mounted in the adjustable
frequency drive.
6-62 Terminal X30/8 Max. Scale
Range: Function:

[0.00 -
200.00 %]
Scales the maximum output of the selected
analog signal on terminal X30/8. Scale the
value to the desired 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 desired
output current at a value between 0%–100%
of the full-scale output, program 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 %
i . e . 10 mA :
20 − 4
10
x 100 = 160 %
6-63 Terminal X30/8 Bus Control
Range: Function:
0.00 % * [0.00 - 100.00 %] Holds the level of Output X30/8 if
controlled by bus.
6-64 Terminal X30/8 Output Timeout Preset
Range: Function:
0.00 % * [0.00 - 100.00
%]
Holds the preset level of Output X30/8.
In case of a bus timeout and a timeout
function is selected in 6-60 Terminal
X30/8 Output, the output will preset to
this level.
3.8.8 6-7* Analog Output 3 MCB 113
Parameters for configuring the scaling and limits for analog
output 3, Terminal X45/1 and X45/2. Analog outputs are
current outputs: 0/4 – 20 mA. Resolution on analog output is
11 bit.
