6-46 Term. X30/12 Filter Time Constant
Range:
Function:
0.001 s
*
[0.001 - 10
s]
NOTICE
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.
3.7.6 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:
Function:
Select the function of terminal 42 as an
analog current output. Depending on the
selection, the output is either a 0–20 mA or
4–20 mA output. The current value can be
read out in the LCP in
parameter 16-65 Analog Output 42 [mA]
