Communications Via As-I - Siemens Sinamics G110M Operating Instructions Manual

Installation
4.4 Connecting the inverter to the fieldbus
Procedure
To change the bus address, proceed as follows:
1. Set the address using one of the subsequently listed options:
– using the address switch
– from an operator panel using parameter p0918
– in STARTER using screen form "Control Unit/Communication/PROFIBUS" – or using
2. Switch off the inverter supply voltage.
3. Wait until all LEDs on the inverter go dark.
4. Switch on the inverter supply voltage again.
Your settings become active after switching on.
You have now changed the bus address.

Communications via AS-i

General information
The inverter operates based on the extended AS-i specification V3.0.
The signaling is made as Manchester-coded current pulses superimposed on the 28 V
supply. Decouple the 28 V supply with inductances so that the receivers can decouple the
transferred messages.
The Control Unit power consumption is approx. 90 mA provided you do not use any digital or
analog inputs. When you use digital and analog inputs, the power requirement can be as
high as 300 mA.
The inverter supports the Single Slave and Dual Slave modes.
In Single Slave mode, the inverter has an address in the AS-i network over which four bits
are transferred. In Dual Slave mode, each inverter has two AS-i addresses over each of
which four bits are transferred.
In the Single Slave mode, communication is realized in accordance with protocol 7.F.E. In
the Dual Slave mode, communication is realized in accordance with protocols 7.A.5 and
7.A.E.
