IDN 392 (S-0-0392) Velocity Feedback Filter Time Constant
The velocity feedback is passed through a first order low pass filter before being applied to the velocity loop. The filter is useful for improving the step response and operational smoothness, particularly for very small, highly dynamic motors.
If the filter’s time constant is too low, then the motor may run roughly.
If the filter’s time constant is too high, then the motor’s response may be soft and unstable.
The filter’s time constant may be adjusted in intervals of 100 (s.
