6-61 Term. X30/8 Output Min Scale
Value:
0.00 - 200 %
Function:
Scales the minimum output of the selected analog
signal on terminal X30/8. Scale the minimum val-
ue as a percentage of the maximum signal value,
i.e. 0 mA (or 0 Hz) is desired at 25% of the max-
imum output value and 25% is programmed. The
value can never be higher than the corresponding
setting in par. 6-62 if value is below 100%.
This parameter is active when option module MCB
101 is mounted in the frequency converter.
6-62 Term. X30/8 Output Max Scale
Value:
0.00 - 200 %
Function:
Scales the maximum output of the selected ana-
log signal on terminal X30/8. Scale the value to
the desired masimum 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 be-
tween 0 - 100% of the ful-scale output, program
the percentage value in the parameter, i.e. 50%
= 20 mA. If a current between 4 and 20 MA is de-
sired at maximum output (100%), calculate the
percentage value as follows:
m A desired maximum current x
20 /
