DET-618C
Function:
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 AN-62 Terminal X30/8
Max. Scale if value is below 100%.
This parameter is active when option module
OPCGPIO General Purpose I/O Option Module is
mounted in the frequency converter.
Function:
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 ful-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:
100 %

100 = 160 %
Function:

Function:
In case of a bus timeout and a timeout
function is selected in AN-60 Terminal X30/8
Output, the output will preset to this level.
