Each of the 32 frequency bands can be configured to one of the following characteristic values.
32个频带中的每个频带可以被配置为以下特征值之一。
Characteristic value 特征值 |
Description 描述 |
|---|---|
FrequencyBandRmsAccEnvelope 频带的加速度包络信号有效值 |
The RMS value formed from the envelope signal of the oscillation acceleration in a freely selectable frequency range. 在可自由选择的频率范围内，由振荡加速度的包络信号形成的有效值。 |
FrequencyBandRmsVelEnvelope 频带的速度包络信号有效值 |
The RMS value formed from the envelope signal of the oscillation velocity in a freely selectable frequency range. This frequency band is only calculated if the EnableVelocityCalculation bit (configuration in register SensorConfig) is set for the respective channel; otherwise, 0 is output. 在可自由选择的频率范围内，由速度的包络信号形成的有效值。仅当为相应通道设置了启用速度计算（EnableVelocityCalculation）位（寄存器 SensorConfig中的配置) 时，才计算该频带；否则，输出0。 |
FrequencyBandRmsAccRaw 频带的加速度原始信号有效值 |
The RMS value formed from the raw signal of the oscillation acceleration in a freely selectable frequency range. 在可自由选择的频率范围内，由振荡加速度的原始信号形成的有效值。 |
FrequencyBandRmsVelRaw 频带的速度原始信号有效值 |
The RMS value formed from the raw signal of the oscillation velocity in a freely selectable frequency range. 在可自由选择的频率范围内，由速度的原始信号形成的有效值。 |
FrequencyBandNoiseAccEnvelope 频带的加速度包络信号噪声 |
The noise value formed from the envelope signal of the oscillation acceleration in a freely selectable frequency range. 在可自由选择的频率范围内，由振荡加速度的包络信号形成的噪声值。 |
FrequencyBandNoiseVelEnvelope 频带的速度包络信号噪声 |
The noise value formed from the envelope signal of the oscillation velocity in a freely selectable frequency range. This frequency band is only calculated if the EnableVelocityCalculation bit (configuration in register SensorConfig) is set for the respective channel; otherwise, 0 is output. 在可自由选择的频率范围内，由速度的包络信号形成的噪声值。仅当为相应通道设置了启用速度计算（EnableVelocityCalculation）位（寄存器 SensorConfig中的配置) 时，才计算该频带；否则，输出0。 |
FrequencyBandNoiseAccRaw 频带的加速度包原始信号噪声 |

FrequencyBandNoiseVelRaw 频带的速度原始信号噪声 |
The noise value formed from the raw signal of the oscillation velocity in a freely selectable frequency range. This frequency band is only calculated if the EnableVelocityCalculation bit (configuration in register SensorConfig) is set for the respective channel; otherwise, 0 is output. 在可自由选择的频率范围内，由速度的原始信号形成的噪声值。仅当为相应通道设置了启用速度计算（EnableVelocityCalculation）位（寄存器 SensorConfig中的配置) 时，才计算该频带；否则，输出0。 |
The measured damage frequency may vary slightly from the expected frequency. It must therefore be ensured that the frequency band is wide enough to monitor the harmful frequency to compensate for this deviation.
测量的故障频率可能与预期频率略有不同。因此，必须确保频带足够宽，从而补偿这种偏差，以监测故障频率。
The maximum permissible deviation has been defined as 1/2% of the maximum drive frequency. Since the deviation could occur in either the positive or negative direction, it must be counted twice. This results in the following formula:
允许的最大偏差被定义为最大驱动频率的 0.5%，由于该偏差可能发生在正方向或负方向，所以必须计算两次。这就形成了以下公式：
Total range of frequency band = 2 * 1/2% * max. drive frequency [Hz]
频带总带宽 = 2 * 0.5% * 最大的驱动频率 [Hz]
Depending on the MaxFrequency selected, a least 3 lines should be configured within each frequency band.
The first lines to the left and right of the configured frequency band are included proportionally based on their distance from the frequency band (see figure in Frequency bands).
根据选择的最大频率（MaxFrequency ）, 每个频带内至少应配置 3 条线。
在配置的频段左右两边的第一条线会根据它们与频段的距离按比例包括在内 (见 Frequency bands) 图例。
At a maximum drive frequency of 50 Hz, a frequency band should be set at 10 Hz.
10 Hz ± (0.005 * 50 Hz) = At least 9.75 Hz lower and 10.25 Hz upper frequency band limits
在最大驱动频率为 50 Hz 时, 频带应设置为 10 Hz。
10 Hz ± (0.005 * 50 Hz) = 9.75 Hz 的频带下限频率 和 10.25 Hz 的频带上限频率
