过程微调
使用简单的低通滤波器来消除反馈电路中的不期望噪声。低通滤波器的截止频率由参数184[PI Lpass Filt BW]设置。典型值范围为15…20 rad/sec。速度环路在速度误差项产生后使用二阶低通滤波器。二阶低通滤波器的截止频率由参数89[Spd Err Filt BW]决定。该参数的典型值是速度环路带宽的五倍（参数90[Spd Reg BW]）。Pow中使用了几个超前滞后滤波器700秒。超前滞后滤波器有两项。第一项是滤波器增益（Kn），第二项是滤波器频率（Wn）。滤波器可用作“滞后”，以消除进入控制回路的噪声。过滤器可用作提高系统整体性能的“先导”。为了消除噪声（滞后），使用轻型或重型过滤器。使用导程函数：•将Wld设置为等于所需导程（弧度/秒）•将Wlg设置为等于扭矩参考具有用于消除共振信号的陷波滤波器。陷波频率由参数118[陷波滤波器频率]设置。该频率设置为以赫兹为单位的机械共振。
详细驱动配置
操作快速启动快速启动功能用于尽快启动旋转电机，并在对负载或速度影响最小的情况下恢复正常运行。当驱动器在其正常模式下启动时，它最初应用0 Hz的频率，并逐渐达到指令速度。如果在电机已经旋转的情况下以该模式启动驱动器，将产生大电流。如果限流器不能快速反应，可能会导致过电流跳闸。如果驱动启动时旋转电机上有残余电压，则过电流跳闸的可能性会进一步增加。即使限流器足够快以防止过电流跳闸，同步发生和电机达到其所需频率可能需要不可接受的时间。此外，应用程序受到更大的机械应力，增加了停机时间和维修成本，同时降低了生产率。无传感器快速启动功能实现了一种频率搜索算法，该算法搜索转子速度，当找到时，在转换到正常操作之前为电机提供通量上升时间。
Process tuning
A simple low-pass filter is used to eliminate the undesired noise in the feedback circuit. The cut-off frequency of the low-pass filter is set by parameter 184 [PI Lpass Filt BW]. Typical values range from 15... 20 rad/sec. The velocity loop uses a second-order low-pass filter after the velocity error term is generated. The cut-off frequency of the second-order low-pass filter is determined by parameter 89 [Spd Err Filt BW]. The typical value of this parameter is five times of the speed loop bandwidth (parameter 90 [Spd Reg BW]). Several lead lag filters are used in Pow for 700 seconds. Lead lag filter has two items. The first term is the filter gain (Kn), and the second term is the filter frequency (Wn). The filter can be used as a "lag" to eliminate the noise entering the control loop. The filter can be used as a "leader" to improve the overall performance of the system. To eliminate noise (hysteresis), use light or heavy duty filters. Use lead functions: • Set Wld equal to the desired lead (radians/second) • Set Wlg equal to the torque reference has a notch filter for eliminating resonance signals. The notch frequency is set by parameter 118 [notch filter frequency]. This frequency is set to mechanical resonance in hertz.
Detailed drive configuration
The operation quick start quick start function is used to start the rotating motor as soon as possible and resume normal operation with minimal impact on load or speed. When the drive starts in its normal mode, it initially applies a frequency of 0 Hz and gradually reaches the commanded speed. If the driver is started in this mode when the motor has rotated, a large current will be generated. If the current limiter does not respond quickly, it may cause overcurrent tripping. If there is residual voltage on the rotating motor when the drive starts, the possibility of overcurrent tripping will be further increased. Even if the current limiter is fast enough to prevent overcurrent tripping, it may take unacceptable time for synchronization to occur and the motor to reach its desired frequency. In addition, applications are subject to greater mechanical stress, increasing downtime and maintenance costs, while reducing productivity. The sensorless quick start function realizes a frequency search algorithm, which searches the rotor speed, and when found, provides the motor with flux rise time before switching to normal operation.
