4.4.4 Communications via AS-i
General information
The converter 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 converter supports the Single Slave and Dual Slave modes.
In Single Slave mode, the converter has an address in the AS-i network over which four bits are
transferred. In Dual Slave mode, each converter 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 converter via AS-i, the following options are available for
commissioning the converter: Using parameter p0015, select which default setting you wish to
accept:
Table 4-8 p0015 (macro drive unit)
p001
5 = Designation Meaning
30 Default setting 30 - single slave mode, standard addressing Single slave mode, where the control system specifies a
fixed frequency
31 Default setting 31 - dual slave mode with fixed setpoints Dual slave mode, where the control system specifies a
fixed frequency
32 Default setting 32 - single slave mode, modified addressing Default setting 32 - Single Slave mode, modified address‐
ing:
34 Default setting 34 - dual slave mode with "ON/OFF1", "OFF2" Dual Slave mode with "ON/OFF1", "OFF2", speed setpoint
from the control system
Details about the default settings are provided in the operating instructions of your converter.
