3.2 Speed setpoint filter

3.2Speed 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.
