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.
4.7.6 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.
