7.7 Drive control via AS-i
Macro 31: AS-i Dual Slave with fixed setpoint
The control accesses the two slaves of the converter each via four bits.
Via Slave 2, in accordance with profile 7.A.E, the control specifies the speed setpoint via the
motor control bits (AS-i.DO0 ... AS-i.DO2).
Via Slave 1, the control sends data in cyclical or acyclical mode, in accordance with profile
7.A.5.
The control requires one bit per slave in order to specify the slave.
Macro 31, Slave 2 with profile 7.A.E: Control → Converter
• AS-i.DO0
• AS-i.DO1
• AS-i.DO2
• AS-i.DO3
If the control specifies the speed setpoint, the converter replies:
Macro 31, Slave 2 with profile 7.A.E: Converter → control
• 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.

→ Time signal for the CTT2 (Combined Transaction Type 2) transfer from
the AS-i master
→ Data bit for the CTT2 transfer, four bytes cyclically or acyclically via PIV
(parameter channel). The reading and writing of parameters is possible
via the PIV. Because data is transferred bit-by-bit, the read and write
process is very slow.
