Lenze i550 Series - Profibus

PROFIBUS
The network must be terminated with a resistor at the physically rst and last node.
Acvate the bus terminang resistor at these nodes in the bus connecon plug.

Basic network sengs
Use the DIP switch to set the
staon address.
The baud rate is detected automacally.

OFF OFF ON OFF ON ON ON
Staon address = 16 + 4 + 2 + 1 = 23
Do not set staon address = 126 and staon address = 127. These staon addresses are invalid.
