[0.00 -

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.

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
