Single Slave Mode - Siemens SINAMICS G110M Function Manual

7.2

Single Slave mode

In Single Slave mode, four bits are available for the communication between the AS-i master
and the inverter. The four bits are used to transfer process data. In parallel, the control can
start a diagnostic request via AS-i.P0.
The following default settings are available; both work with profile 7.F.E.
● Default setting 30: Standard Single Slave mode
● Default setting 32: Modified Single Slave mode
Default setting 30: Standard Single Slave mode
In standard addressing, the control specifies the speed setpoint via the motor control bits
(AS-i.DO0 ... AS-i.DO3).
Control -> inverter
• AS-i.DO0
• AS-i.DO1
• AS-i.DO2
• AS-i.DO3
Inverter -> control
If the control specifies the speed setpoint, the inverter replies:
• p2080[0] = 53.13
• p2080[1] = 899.11 ->
• p2080[2] = 722.0
• p2080[3] = 722.1
If the control sends a diagnostic request via AS-i.P0, the inverter replies with the currently
pending fault or alarm messages.
