Meaning 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.

Order cannot be executed (with error number in PWE2)
* Only for PPO type 2 and PPO type 4
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.
