For this, the following FI parameters must be set as follows:

P480 [01] Bus IO In Bit 0

1 = Enable right

P480 [02] Bus IO In Bit 1

2 = Enable left

P480 [03] Bus IO In Bit 2

8 = Parameter switch-over

P480 [04] Bus IO In Bit 3

12 = Error acknowledgement

P481 [01] Bus IO Out Bit 0

2 = Inverter operating

P481 [02] Bus IO Out Bit 1

7 = Error

P509 interface

0 = Control terminals or keyboard control

P543 Bus actual value 1

12 = Bus IO Out Bits 0-7

P546 Bus setpoint 1

17 = Bus IO In Bits 0-7

For the switch-over of the parameter set it should be noted that the parameters dependent on the parameter
set, e.g. P543 and P546 are also accordingly parameterised onto Bus IO Bits.

AS interface binary values (Digital inputs and outputs)

The following example purely serves for the I/O expansion of the control signals and can also be operated
without the AS interface master.
For example, a frequency inverter is to be enabled for the directions of rotation right and left via the digital AS
interface In Bits (Sensor Dig), and the direction of rotation changed via the second sensor input. In addition, a
setpoint increase is to be made via fixed frequency 1. An error acknowledgement is to be performed with the
fourth and last In Bit (Sensor Dig). The operation and the error indication of the frequency inverter are to be
output via the first two of the four digital AS interface Out Bits (Actuator Dig).

For this, the following FI parameters must be set as follows:

P429 Fixed frequency 1

e.g. 10 Hz

P480 [05] Bus IO In Bit 4 (Sensor Dig In 1)

1 = Enable right

P480 [06] Bus IO In Bit 5 (Sensor Dig In 2)

3 = Reverse direction of rotation

P480 [07] Bus IO In Bit 6 (Sensor Dig In 3)

4 = Fixed frequency 1

P480 [08] Bus IO In Bit 7 (Sensor Dig In 4)
