Output Max Value could be out-of-range or unsafe. Therefore the Output Max
Value parameter must be written to with the desired setting after a mode change.
The next PDO-RX (MOSI) will then reset the command to the desired output
value.
Analog Filter Rates
The filter applied to each analog input provides an exponential response, and
the Filter Gain parameter responds exponentially as well.
Typically an exponential filter is known by its Time Constant (TC), which
is how long it takes the filter to respond to a step input and reach 63% of its
final value. It takes approximately 5 TCs before the filtered signal reaches its full
output. The table below provides a way to estimate filter response.
