Function:
0.00 - par. Sets the analog input scaling value to
correspond to the low reference/
feedback value set in 6-44 Term.
X30/12 Low Ref./Feedb. Value.
Function:
par. 6-40 - Sets the analog input scaling value to
correspond to the high reference/
feedback value set in 6-45 Term.
X30/12 High Ref./Feedb. Value.
Function:
Sets the analog output scaling
value to correspond to the low
voltage value set in 6-40 Terminal
X30/12 Low Voltage.
Function:
Sets the analog input scaling
value to correspond to the high
voltage value set in
6-41 Terminal X30/12 High
Voltage.
Function:
A 1 st order digital low pass filter time
constant for suppressing electrical
noise on terminal X30/12.
6-46 Term. X30/12 Filter Time Constant
cannot be changed while the motor is
running.
Function:
This parameter makes it possible to disable the
Live Zero monitoring. E.g. to be used if the
analog outputs are used as part of a decentral
I/O system (e.g. when not part of any frequency
converter related control functions, but feeding a
Building Management System with data)

3.8.6 6-5* Analog Output 1
Parameters for configuring the scaling and limits for
analog output 1, i.e. Terminal 42. Analog outputs are
current outputs: 0/4-20mA. 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.
