The phase shift is 0... 180 °. Figure 14 Automation publication PFLEXRM002DENE August 2013 Chapter 1 Detailed Drive Configuration and Operating Speed Control Regulator has a second-order low-pass filter. The filter is located after the speed error signal. The interrupt frequency is set by parameter 89 [Spd Err Filt BW]. The interrupt frequency is set to five times the speed loop bandwidth. This filter is used to attenuate any high-frequency noise that cannot be controlled by the speed loop. The lead lag filter PowerFlex 700S includes a universal lead lag filter. The filter has the following Laplace transfer function: Kn is the gain term of the filter, and Wn is the frequency term of the filter. Lead lag filter "lag" When Kn is less than 1 (Kn1), the lead lag filter operates as a lead filter. The original equation is rewritten to a term that can be used to utilize the derivative function. Wn is divided throughout the equation. Two new terms have been developed.

The hysteresis term (Wlg) is used to display the hysteresis of the filter. Figure 17 shows the Bode diagram of the boot function. The preceding term is used to offset the lag in the system. The speed loop bandwidth is represented as a low-pass filter or hysteresis in the position loop. The leading filter can be used to eliminate the speed loop hysteresis and replace it with a faster hysteresis.
