● Reading working status information from frequency converter (such as
run, rotation direction, rotation speed, error message, etc.).
● Reading or modifying converter parameters.
● Resetting frequency converter in case of fault.
Network Structure
PROFIBUS network of Rexroth Fv series frequency converters through con‐
nection via PROFIBUS adapter is shown in fig. 12-24 "Fv converter
PROFIBUS network" on page 192 .

Bus Terminal Resistor
Switch S1 on PROFIBUS adapter is used to switch On/Off built-in bus termi‐
nal resistor of the adapter. The bus terminal resistor can prevent signal re‐
flection of bus cable end. If the adapter is the last node or the first node of the
network, S1 must be at On status. When PROFIBUS D-sub connector with
built-in terminal resistor (for example, Siemens 6ES7972-0BA12-0XA0) is
used, the built-in terminal resistor of the adapter must be disconnected.
