Single slave mode

In Single Slave mode, four bits are available for the communication between the AS-i master and
the converter. 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).

Converter -> control
If the control specifies the speed setpoint, the converter 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 converter replies with the currently
pending fault or alarm messages.
