Description
External control signals are required for an inverter to be able to operate autonomously.
These signals can be entered using a serial interface as well as using digital inputs (see
figure below). The SINAMICS G120 has depending on CU variant up to 9 digital inputs which
can be expanded by using the 2 analog inputs. The digital inputs can be freely programmed
to create a function. Regarding the programming, it is possible to directly assign the function
using parameters P0701 ... P0713 or to freely program the function using BICO technology.
Figure 8-10
The number of available digital inputs is displayed in parameter r0720. The logical states of
the digital inputs can be de-bounced using P0724 and read-out using parameter r0722
(BICO monitoring parameter). Further, this parameter is used for BICO parameterization of
the digital inputs (refer to BICO parameterization in the following section).
