Converter → control
The converter sends as response:
• p2080[0] = 899.0 → AS-i.DI0 Ready to switch on / diagnostic request
• p2080[1] = 807.0 → AS-i.DI1 Control priority
• p2080[2] = 722.0 → AS-i.DI2 State DI0
• p2080[3] = 722.1 → AS-i.DI3 State DI1
If the control sends a diagnostic request via AS-i DI0, the converter replies with the currently
pending fault or alarm messages.
• AS-i DI0 = 1, pending alarm messages are replied.
• AS-i DI0 = 0, pending fault messages are replied.

Scaling factors for the speed
The scaling factor is specied via AS-i.P0…AS-i.P3.
This means, if the control species a scaling factor, it accepts simultaneously the sent value
consisting of AS-i.P0…AS-i.P3 as new scaling factor.
• AS-i.P0 Scaling factor bit 0
• AS-i.P1 Scaling factor bit 1
• AS-i.P2 Scaling factor bit 2
• AS-i.P3 Scaling factor bit 3

7.7.2 Dual Slave mode
In Dual Slave mode, eight bits are available for the communication between the AS-i master and
the converter. The eight 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 possible:
• Macro 31: AS-i Dual Slave with xed setpoint
• Macro 34: AS-i Dual Slave with eldbus setpoint
