Communication Via As-I - Only For G110M - Siemens SINAMICS G110M Function Manual

Communication via AS-i - only for G110M

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.
Default settings for commissioning
To configure the communication of the inverter via AS-i, the following possibilities are
available for commissioning the inverter:
● Default setting 30 - Single Slave mode, standard addressing
Single Slave mode with specification of a fixed frequency via the control
● Default setting 31 - Dual Slave mode with fixed setpoints
Dual Slave mode with specification of a fixed frequency via the control
● Default setting 32 - Single Slave mode, modified addressing:
Single Slave mode with "ON clockwise / OFF1", "ON counter-clockwise / OFF1", speed
setpoint via CDS0 or CDS1
● Default setting 34 - Dual Slave mode with "ON/OFF1", "OFF2"
Dual Slave mode with "ON/OFF1", "OFF2", speed setpoint via control
Details about the default settings are provided in the operating instructions of your inverter.
