Note
When switching on and off the rated load voltage (L+), wrong intermediate values
can occur across the output for approximately 10 ms.
Parameter
You will find a description of the general procedure for assigning parameters to
analog modules in Section 4.7.
You will find an overview of the programmable parameters and their default values
in Table 4-42, on page 4-43.
