Connecting the Inverter to AS-i network

Connecting the Inverter to the AS-i network
Assignment of the M12 connector to connect to the AS-i network
The SINAMICS G110D Inverter has one M12 AS-i connection to allow connection the the
AS-i network. The pin assigment of the M12 connector is shown in the table below.
Table 6- 52
Recommended AS-i connector
We recommend the following AS-i M12 branch connector for connection to the AS-i network.
● AS-i M12 connection kit (3RK1901-1NR21)
Permissible cables and cable lengths
AS-i yellow data cable - 3RX9013-0AA00
AS-i black power cable - 3RX9023-0AA00
The maximum length of any one segment on the AS-i network is normally 100 m (328 ft).
However there are a number of devices that allow the length of network segments to be
extended.
Repeater
A repeater allows the maximum cable length to be extended to 300 m (984 ft) using the
maximum of two repeaters. Slave nodes can be used on both sides of a repeater.
Extender
The extender allows the distance between the AS-i master and an AS-i segment of the
network to be extended to a maximum of 100 m (328 ft). With repeaters connected in
parallel, a cable length significantly longer than 300 m (984 ft) can be achieved. The
maximum span is 500 m (1640 ft). The only limitation of the extender is that slaves can only
be used downstream from the extender.
Extension plug
Using the extension plug, the maximum possible cable length in an AS-i segment can be
doubled from 100 m (328 ft) to 200 m (656 ft). The extension plug is a passive device and is
