External control signals are required for a drive to be able to operate. These signals can be entered
through the serial interface as well as using digital inputs.
MICROMASTER 440 has 6 digital inputs which can be expanded to a total of 8 by using the 2 analog
inputs. The digital inputs can be freely programmed to create a function. It is possible to directly assign
a pre-designed function using parameters P0701 - P0708 or to build your own function using BICO
technology.
This document will only cover the use of the pre-designed functionality.

The diagram above illustrates that you have external switches. You choose whether the signals are
active high or active low (P0725). You choose the de-bounce time to filter out noisy switches (P0724),
you then assign a function to that input according to the table 5.8 below (P0701-P0708);
NOTE
r0722 is a digital representation of the status of the 6 (+2) digital inputs – this parameter should be
used to check that your signals are coming through to the drive.
