2. Configuration word (Parameter P[10])
Configuration of the regulator takes place by setting the individual bits of parameter P[10]. Each of them
enables or disables at least one function, on the basis of the fact that its value is respectively 1 or 0.
If the "DSR Terminal" programme is used (see the Chapter on "Use of DSR Terminal monitoring and
programming software"), the setting is facilitated with the
Configuration menu, where each box enables or
disables a function and corresponds to the respective bit.
Alternatively, the DER1 can be configured by directly setting the value of the P[10] parameter; in this case
the value is calculated before entry, summing the numbers indicated in the column "Value" of Table 7,
corresponding to the functions it is desired t enable.
For example, the default configuration calls for the bits B2, B4 and those from B8 to B12 to be enabled.
The corresponding value is therefore: P[10]=4+16+256+512+1024+2048+4096=7956.
