Active Output Terminal Functions
The following table shows all possible terminal functions for the virtual terminals. Generally, only
those output terminal functions can be used which are functionally available. As, for instance,
simultaneous operation of the fieldbus and the synchronous operation is not possible (due to terminal
assignment), the synchronous operation terminal functions cannot be used via the fieldbus.

Integrated Input/Output-Module Functionality
The input and output terminals of the inverter can be used for digital input/output of sensor/actor
signals via the fieldbus system. This way the inverter MOVITRAC
®
31.. additionally takes on the
functionality of an input/output-module on the fieldbus.
Consequently the higher-level control can read in the sensor signals on the inputs of the inverter and
can control an actor via an output terminal of the inverter.

Scale of functions
In the basic design the inverter MOVITRAC
®
31.. is equipped with 6 digital input terminals and 2
digital output terminals. For the I/O-module functionality all free programmable terminals can be
used. Consequently the higher-level control is provided with maximum
5 digital input terminals and
1 digital output terminal.
