Range: Function:
0.000
*
[-999999.999 -
999999.999 ] Sets the analog output scaling
value to correspond to the low
voltage value set in
6-40 Terminal
X30/12 Low Voltage .
6-45 Term. X30/12 High Ref./Feedb. Value
Range: Function:
100.000
*
[-999999.999 -
999999.999 ] Sets the analog input scaling
value to correspond to the high

6-46 Term. X30/12 Filter Time Constant
Range: Function:
0.001 s
*
[0.001 - 10.000
s]
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.
6-47 Term. X30/12 Live Zero
Option: 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 – 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.
6-50 Terminal 42 Output
Option: Function:
Select the function of Terminal 42 as
an analog current output. A motor
current of 20 mA corresponds to I
max
.
