*
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.
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 to 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. Depending on the
selection the output is either a 0-20mA or
4-20mA output. The current value can be
read out in in parameter 16-65 Analog Output
42 [mA].
[0] No When no signal on the analog output.
