1st order phase correction filter

The 1^st order phase correction filter attenuates all frequencies above the limit frequency entered. Select a servo drive (1) in the TwinCAT System Manager, start the TCDriveManager (2), click on the respective axis (3) and select the "Current command value filter" (4).

A maximum of four filters are evaluated, which can be parameterised independently of one another. In area (6), activate the filter that you would like to occupy with the phase correction filter. The cycle time of the velocity controller is indicated in field (7). The "QMath Factor" (8) determines the scaling of the filter input parameter. With the current filter implementation the maximum possible resolution is achieved with the default value "30".

Now select "Phase correction filter 1. order" (33) from the drop down menu.
