5.2.2 Activating the bus terminating resistor
The PROFIBUS must be terminated by a bus terminating resistor at the first and last physical bus
station.
The bus terminating resistor in the bus connector of the bus cable is activated by means of a switch.
PROFIBUS cables with integrated bus terminating resistor are offered by several cable
manufacturers.

Note!
If you want to disconnect individual bus stations, ensure that the bus terminators at the
cable ends remain active.
Please observe that the bus termination is not active any longer if ...
• the bus connector has been disconnected;
• the voltage supply of the Servo Drive 9400 has been switched off;
• the
External voltage supply ( 28) of the communication module has been switched
off.
