1.1 Introduction to Parameters
1.1.1 Explanation of list of parameters
The layout of the parameter description is as follows.
Fig. 1-1 Read-only parameter
Fig. 1-2 Write parameter
Parameter number
Indicates the relevant parameter number. The numbers used are 4 to 5-digit num-
bers. Numbers prefixed with an “r” indicate that the parameter is a “read-only”
parameter, which displays a particular value but cannot be changed directly by
specifying a different value via this parameter number.
All other parameters are prefixed with a “p”. The values of these parameters can
be changed directly in the range indicated by the “Min” and “Max” settings in the
header. If these values have a physical unit, it is shown in brackets.
[index] indicates that the parameter is an indexed parameter and specifies the
range of indices available.
.0...15 indicates that the parameter has several bits, which can be evaluated or
connected individually.
CU/PM variants
Indicates for which Control Units and/or Power Modules the parameter is valid. If
no CUs or PMs are listed the parameter is valid for all variants.
