FC 300 Design Guide
Function:
Sets the analog input scaling value to correspond
to the minimum reference feedback value
(set in par. 3-02).
6-45 Term. X30/12 High Ref./Feedb. Value
Range:
Par. 6-44 to 1000000.000
Function:
Sets the analog input scaling value to correspond
to the maximum reference feedback value
(set in par. 3-03).
6-46 Term. X30/12 Filter Time Constant
Range:
0.001 - 10.000 s
Function:
st
A 1 order digital low pass filter time constant for
suppressing electrical noise on terminal X30/12.
Par. 6-46 cannot be changed while the
motor is running.
6-5* Analog Output 1 (MCB 101)
"
Parameters for configuring the scaling and limits
for analog output 1, i.e. Terminal 42. Analog
outputs are current outputs: 0/4 – 20 mA.
Common terminal (terminal 39) is the same
terminal and has the same electrical potential for
analog common and digital common connection.
Resolution on analog output is 12 bit.

Function:
Select the function of Terminal 42 as an
analog current output.
6-51 Terminal 42 Output Min Scale
Range:
0.00 – 200%
Function:
Scale the minimum output of the selected
analog signal at terminal 42, as a percentage
of the maximum signal value. E.g., if 0 mA
(or 0 Hz) is desired at 25% of the maximum
output value, then program 25%. Scaling
values up to 100% can never be higher than the
corresponding setting in par. 6-52.
6-52 Terminal 42 Output Max Scale
Range:
000 – 200%
Function:
Scale the maximum output of the selected analog
signal at terminal 42. Set the value to the maximum
value of the current signal output. Scale the output
to give a current lower 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
