Description
Selects faults that are automatically reset. The parameter is a
16-bit word with each bit corresponding to a fault type.
Whenever a bit is set to 1, the corresponding fault is
automatically reset.
Note: The autoreset function is only available in external
control; see section
Local control vs. external control
18).
The bits of the binary number correspond to the following
faults:
