3.8.6 6-5* Analog Output 1
Parameters for configuring the scaling and limits for analog
output 1, that is 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:
110
Function:
NOTICE
[0.005 - 10 s]
This parameter cannot be
adjusted while the motor is
running.
Enter the filter time constant. This
constant is a first-order digital low-
pass filter time for suppressing
electrical noise in terminal X30/12.
A high value improves dampening
but also increases the delay
through the filter.
Function:
This parameter makes it possible to
disable the live zero-monitoring. For
example, to be used if the analog
outputs are used in a decentral I/O
system (when an analog output
does not fulfil any control function,
but feeds a data storage device).
Function:
NOTICE
Values for setting the
minimum reference are found
in open loop
parameter 3-02 Minimum
Reference and for closed loop
parameter 20-13 Minimum
Reference/Feedb.. Values for
maximum reference for open
loop are found in
parameter 3-03 Maximum
Reference and for closed loop
parameter 20-14 Maximum
Reference/Feedb.
This parameter enables the function
of terminal 42 as an analog current
