5.4.1.5.9.7 MinFrequencyEnvelope
Name:
MinFrequencyEnvelope01
This register is used to configure the lowest frequency of the envelope signal to be evaluated for the individual
channels.
This configuration only needs to be set for channels whose EnableVelocityCalculation bit has been set (configured
in the
"SensorConfig" on page 158
register).
Bit EnableVelocityCalculation = 0
The following minimum values based on the maximum frequency (
see "MaxFrequencyEnvelope" on page 185
) are
used: This table shows the minimum MinFrequencyEnvelope based on MaxFrequencyEnvelope:

this lower frequency.
