CHAPTER5 OPERATING

5.2 PKW-part

The parameter part (PKW) is fixed to 4 words and can be used for reading and/or updating the parameters in the inverter one by one. Requests and responses is a handshake procedure and cannot be batched, meaning that if the master sends out a read/write request, it has to wait for the response, before it sends a new request.

The PKW is further divided into three parts; PKE- Parameter ID (2 bytes), IND – Sub-index (2 bytes) and PWE- Parameter value (4 bytes).
