The servo-loop bandwidth
A measurement, expressed in frequency (hertz), of the range which an amplifier or motor can respond to an input command from DC to -3dB on a frequency sweep. of an axis is the lowest frequency at which the complementary sensitivity response decreases below -3 dB. A higher servo-loop bandwidth A measurement, expressed in frequency (hertz), of the range which an amplifier or motor can respond to an input command from DC to -3dB on a frequency sweep. makes it easier for the axis to reject disturbances at high frequencies, and gives you a faster rise time.
