Fig. 5: Bus termination at the beginning and end of a PROFIBUS segment
As the bus terminating resistors can be connected on the FFP 31 of the frequency inverter, it is not
necessary to use a type D connector with integrated terminating resistors. With the appropriate
DIP switch on the option pcb (
→
Fig. 6) set to the “on” position the bus terminating resistors (in
accordance with EN 50170 V2 / DIN E 19245 Part 3) can be connected.
The bus termination for cable type A is implemented in accordance with EN 5170 V2 /DIN E 19245
Part 3.

Setting the Station Address
The PROFIBUS station address is set with the DIP switches on the option pcb. PROFIBUS supports
the address range from 0 - 125. The address 126 is reserved for PROFIBUS-DP and is for setting
the address via the bus interface. This feature is, however, not supported by the MOVITRAC

The address 127 is reserved for the broadcast service. Fig. 7 shows how the station address is set
with the DIP switches.
