3.2 Speed setpoint filter

3.2 Speed setpoint filter
The two speed setpoint filters are identical in structure and can be used as follows:
● Bandstop
● Low-pass 1st order (PT1) or
● Low-pass 2nd order (PT2)
Both filters are activated via parameter p1414.x. Parameters p1415 and p1421 are used to
select the filter elements.
