超前滞后滤波器
该系统的响应为5 rad/sec。通过添加超前滞后滤波器，系统响应增加到50 rad/sec。图18添加到系统的超前滤波器位置回路速度参考有超前滞后滤波器。参数为Kn=参数25[STrim2 Filt Gain]，Wn=参数26[SpdTrim2 Filt BW]。典型的用途是将超前函数（Wld）设置为速度带宽（参数90[Spd Reg BW]），将滞后函数（Wlg）设置为超前项的大约五倍。陷波滤波器陷波滤波器用于去除特定频率。在模拟输入和输出上，可以使用陷波滤波器来消除从相邻的120V数字输入和输出线接收的任何60Hz噪声。PowerFlex 700S具有陷波滤波器，用于消除机械齿轮系产生的任何共振信号。机械齿轮系由两个质量（电机和负载）和弹簧（两个负载之间的机械耦合）组成。

Lead lag filter
The response of the system is 5 rad/sec. By adding a lead lag filter, the system response is increased to 50 rad/sec. Figure 18 The lead filter position loop speed reference added to the system has a lead lag filter. The parameters are Kn=parameter 25 [STrim2 Fit Gain], Wn=parameter 26 [SpdTrim2 Fit BW]. The typical purpose is to set the leading function (Wld) to the speed bandwidth (parameter 90 [Spd Reg BW]) and the lagging function (Wlg) to about five times the leading term. Notch filter A notch filter is used to remove a specific frequency. On analog inputs and outputs, notch filters can be used to eliminate any 60Hz noise received from adjacent 120V digital input and output lines. The PowerFlex 700S has a notch filter to eliminate any resonance signals generated by the mechanical gear train. The mechanical gear train consists of two masses (motor and load) and springs (mechanical coupling between two loads).
Mechanical gear train
Kspring Bm BL Jm Jload 60 Automation Publication PFLEXRM002DENE August 2013 Chapter 1 Detailed Drive Configuration and Operating Resonance Frequency is defined by the following formula: • Jm is the motor inertia (seconds). • Jload is the load inertia in seconds. • Kspring is the coupling spring constant (rad2/sec). Figure 20 shows a dual mass system with a resonant frequency of 62 rad/sec. One hertz equals 2prad/sec. Figure 20 Resonance inset better shows the resonance frequency. The PowerFlex 700S has a notch filter in the torque reference loop to eliminate such noise in the system. The notch filter frequency is parameter 118 [notch filter frequency]. Since most mechanical frequencies are expressed in Hertz, [notch filter frequency] is also expressed in Hertz. Figure 21 on page 61 shows the same mechanical gear train as Figure 20. [Notch filter frequency] is set to 10.
