Connect

There are two possibilities to connect to the motors.

5.1

Internal bus, B-bus

The first alternative is to connect directly to each motors internal bus, B-
bus. Then you connect the laptop with the USB dongle to the motor (con-
nection X2) via the adapter cable (Festo, D-sub to M12). In the parameter
software you chose B-bus on the interface menu. The tool can only reach
the connected motor. In order to download the ECO software you have to
use this alternative.

5.2

External bus, A-bus

The second alternative is to connect to the external bus (A-bus) instead. In
this case you have to disconnect a line control master because there has
to be only one CANopen master on the network simultaneously. It is impor-
tant to keep the network powered up if the line controller master is discon-
nected.
