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).
