4.2.3 Data format
4.2.3.1 Order label field
The following table lists all the orders which can be transferred from the PROFINET IO controller to the
frequency inverter. The right-hand column contains the response, which is normally sent (response label
positive). Only certain response labels are possible, depending on the order label. In case of error (AK
negative) the inverter will always supply the value 7 in the response label (AK) to the IO controller.
AK Function Response label positive
0 No order 0
1 Order parameter value 1 / 2
2 Change parameter value (word) 1
3 Change parameter value (double word) 2
4 Reserved -
5 Reserved -
6 Order parameter value (array) 4 / 5
7 Change parameter value (array word) 4
8 Change parameter value (array double word) 5
9 Order the number of array elements 6

Table 21 Orders from the controller with the associated response label of the inverter
The following table lists all the orders which can be transferred from the controller to the frequency inverter
or the technology units. The right-hand column contains the response, which is normally sent (response
label positive). Only certain response labels are possible, depending on the order label. In case of error (AK
negative) the inverter always supplies the value 7 in the response label (AK) to the PROFINET IO controller.
