SIMOVERT MASTERDRIVES
A large number of open-loop and closed-loop control functions,
communication functions, as well as diagnostics and operator control
functions are implemented in the software of the converters and
inverters by means of function blocks. These function blocks can be
parameterized and freely interconnected.
The interconnection method can be compared with electrical circuit
engineering where various function units, e.g. integrated circuits or
other components are interconnected by cables.
The difference is, however, that function blocks are interconnected not
by cables, but via software.
Functions are implemented in function blocks. The function scope of
the individual function blocks depends on its special task.
The function blocks are provided with inputs, outputs and parameters
and are processed in time slots.
