Drive control via AS-i

6.7.1

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 interface settings are available; both work with profile 7.F.E.
• Macro 30: AS-i Single Slave with fixed setpoint
• Macro 66: AS-i Single Slave with setpoint from Potentiometer 1 or Potentiometer 2
Macro 30: AS-i Single Slave with fixed setpoint
In standard addressing, the control specifies the speed setpoint via the motor control bits
(AS-i.DO0 ... AS-i.DO3).
Control → Converter
• AS-i.DO0
• AS-i.DO1
• AS-i.DO2
• 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.
