Function-Extension:
RPM actual value filter: The work setting of the associated filter time constants (0x2904) has now been reduced from 0.6 ms to 0.3 ms.
background:
The previous value was mainly based on the quality of the resolver evaluation.
This has since been expanded to include a software filter for the resolver angle, which largely eliminates any disruptive effects.
The subsequent filtering of the actual speed value can therefore be reduced accordingly, which reduces the effective dead time in the control loop.
As a result, the controllers for speed and position can be set somewhat "tighter".
