| FFT || Goal fault filter time || Set time filter for this fault group. Defines how long drive allows exceeding these conditions before entering into fault state. || Normally values between 0-0.5 seconds are safe. Higher value may pose danger to user or equipment as motor is not being stopped soon after error condition. | | FFT || Goal fault filter time || Set time filter for this fault group.

Adjust the value and observe the right side value displaying the hardware value converted to a real world units such as ''revolutions/s''. Make sure [[Granity user guide/Machine|Machine tab]] settings are set-up first to get correct conversion. |
