6-41 Term. X30/12 High Voltage
Value:
Par. 6-40 to 10.0 V
Function:
Sets the analog input scaling value to correspond
to the high reference/feedback value set in par.
6-45.
Term. X30/12 Low Ref./Feedb.
6-44
Value
Value:
-1000000.000 to par. 6-45
Function:
Sets the analog input scaling value to correspond
to the low voltage value set in par. 6-44.
Term. X30/12 High Ref./Feedb.
6-45
Value
Value:
Par. 6-44 to 1000000.000
Function:
Sets the analog input scaling value to correspond
to the high voltage value set in par. 6-41.
6-46 Term. X30/12 Filter Time Constant
Value:
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
Parameters for configuring the scaling and limits
for analog output 1, i.e. Terminal 42. Analog out-
puts are current outputs: 0/4 – 20 mA. Common
terminal (terminal 39) is the same terminal and
has the same electrical potential for analog com-
mon 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
Value:
0.00 – 200%
Function:
Scale the minimum output of the selected analog
signal at terminal 42, as a percentage of the max-
imum signal value. E.g. if 0 mA (or 0 Hz) is desired
at 25% of the maximum output value, then pro-
gramme 25%. Scaling values up to 100% can
never be higher than the corresponding setting in
par. 6-52.
