External control signals are required for a drive converter to be able to operate
autonomously. These signals can be entered via a serial interface as well as also
via digital inputs (refer to Fig. 3-22). MICROMASTER has 3 digital inputs which can
be expanded to a total of 4 by using the 2 analog inputs. The digital inputs, as far
as their assignment, can be freely programmed to create a function. Whereby,
regarding the program, it is possible to directly assign the function via parameters
P0701 - P0704 or to freely program the function using BICO technology.
