14.5.3 Logic Modules
With the Logic Modules function, it is possible to link external digital signals and inter-
nal logic signals of the frequency inverter to one another. Four identical logic modules
are available. These modules can be parameterized independent of one another. The
results of the logic operations can be used for further functions within and outside of
the frequency inverter. In addition to the combinatory logic functions AND, OR and
EXOR, the sequential logic functions RS flip-flop, D flip-flop and Toggle flip-flop are
available.
Each module has two logic inputs and one logic output. The inputs can be parameter-
ized and can be assigned to different signal sources. The signal sources are listed in
the logic table in chapter "Digital Inputs". Additionally, the logic modules can be inter-
connected to each other via the corresponding parameterization. The functionality of
the parameters is the same in each of the four logic modules.
Note: The logic modules are processed internally in the frequency inverter one
after the other depending on their number. For example, logic module 1
is processed before logic module 2.
When designing application-specific logic links, e.g. in the case of time-
critical applications:
− Make sure to comply with the correct order of the logic modules.
− Observe the processing time of 16 ms.
The following table shows the assignment of the parameters to the individual logic
modules:
