With the aid of the minimum frequency process controller the control ratio can also be kept to a
minimum ratio, even with a master value of “zero”, in order to enable adjustment of the
compensator. Further details in P400 and Section 8.2.

Function Bus I/O In Bits
S
The Bus I/O In Bits are perceived as digital inputs. They can be set to the same functions
(P420...425).
[01] = Bus I/O In Bit 0
[02] = Bus I/O In Bit 1
[03] = Bus I/O In Bit 2
[04] = Bus I/O In Bit 3
[05] = Bus I/O In Bit 4
[06] = Bus I/O In Bit 5
[07] = Bus I/O In Bit 6
[08] = Bus I/O In Bit 7
[09] = Flag 1
[10] = Flag 2
[11] = Bit 8 BUS control word
[12] = Bit 9 BUS control word
0 ... 72
[ 0 ]
The possible functions for the Bus In Bits can be found in the table of functions for the digital
inputs P420...425.
For further details, please refer to the manual for the AS interface, BU 0090.
