In this configuration, the RMS value is calculated in a movable window. There are 4 speed inputs available for this (see ActSpeed register). One of the 4 speeds can be selected for each of the 32 frequency bands. In addition, the standardized damage frequency at 60 rpm (FrequencyBandXXDmgFreq60rpm) and a tolerance (FrequencyBandXXTolerance) must be configured. These can be configured separately for each frequency band.

在此配置中，RMS 值是在一个可移动的窗口中计算的，有4个速度输入可用于此操作（请参阅 ActSpeed 寄存器）。可以为32个频带中的每一个频带选择 4 种速度中的一种。I此外，必须配置 60 rpm 的标准化损坏频率 (FrequencyBandXXDmgFreq60rpm) 和容差 (FrequencyBandXXTolerance) 。这些可以为每个频带单独配置。

 

The window in which the RMS value is calculated is determined as follows:

RMS 值的计算窗口确定如下：

Minimum frequency = (speed * standardized damage frequency at 60 rpm) - tolerance

最小频率=（速度在 60 rpm 时的标准损坏频率）- 容差

Maximum frequency = (speed * standardized damage frequency at 60 rpm) + tolerance

最大频率=（速度在 60 rpm 时的标准损坏频率）+ 容差

The standardized damage frequency and tolerance can be entered here in increments of 0.01 Hz.

标准损坏频率和容差的步进值为 0.01 Hz

 

The following signals can be selected for each channel:

T可以为每个通道选择以下信号:

•Raw acceleration signal

加速度原始信号

•Raw velocity signal. Equal to 0 if the speed calculation is disabled.

原始速度信号，如果没有开启速度计算，则为 0 。

•Enveloped acceleration signal

加速度包络值

•Enveloped velocity signal. Equal to 0 if the speed calculation is disabled.

原始速度包络值，如果没有开启速度计算，则为 0 。

 

The harmonic frequencies (integer multiples) of the window can also be included in the calculation. Here, the width of the window is simply retained and the mean frequency of the window is multiplied (by *1, *2, *3, etc.) until the maximum frequency of the set signal and channel is reached.

窗口的谐波频率（整数倍）也可以包括在计算内。在这里，简单地保留窗口的宽度，并将窗口的平均频率相乘（乘以1、2、3等），直到达到配置信号和信道的最大频率。
