The dynamic response of speed loop can be accelerated by increasing speed proportion gain PLTiLTdl reducing speed integration time or increasing speed differentiation time However if speed Motor Speed proportional gain is too big speed integration Switching Freq 0 Schn E time is too little or speed differentiation time is too much all of which will result in big Figure7 17 system overshoot so that oscillation occurs Illustration of PID parameter User should regulate above speed PID parameters according to real load features Usually on the premise of no system oscillation proportion gain can be increased as much as possible and then adjust integration time and differentiation time to enable the system to have quick response with small overshoot To ensure quick response of system at both low speed and high speed PID regulation needs to be conducted at low speed and high speed respectively Below switching frequency 0 the parameters of speed PID Pl Til and Tdl and above switching frequency 1 the parameters of speed PID P2 Ti2 and Tdl If switching frequency 1 F5 06 switching frequency 0 F5 05 then the process is linear transition process from switching frequency 0 to switching frequency 1 as shown in Figure 7 17 1 Be cautious to edit the parameters of F5 00 5 06 2 When setting switching frequency switching frequency 0 5 05 lt switching frequency 1 F5 06 112 User Manual
