Meanings of the values sent in the order label,:
The following table lists all the orders which can be transferred from the master to the 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 master.
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

Meanings of the values sent in the response label,:
AK Function
0 No response
1 Transfer parameter value (word)
2 Transfer parameter value (double word)*
4 Transfer parameter value (array word)
5 Transfer parameter value (array double word)*
7 Order cannot be executed (with error number in PWE2)
* Only for PPO Type 2
As long as an order has not yet been executed, the inverter provides the response to the last order.
Therefore the master must always check whether the received response matches the order sent.
For the plausibility check, the value in the response label (AK), the received parameter number
(PNU) with the corresponding Index (IND) as well as the current parameter value (PWE) can be
used for the description of parameters.
