Figure 6-43 Parameter read request and response
Data Write
A data write request transfers the specified parameter data to the inverter. Since the normal
PKW response is not sent, in the event that the PKW command is not successfully
completed the inverter replies with an error response containing a standard error byte of 'no
error' and a further word value containing the error code.
This request only makes sense for a PKW write command.
