Operation manual

The inverter deletes all response bytes together with the response ID 0. With
response ID 2, the parameter number and the subindex are echoed from the job
in the response. The inverter continues sending the complete response until the
master formulates a new job. With read accesses to indicator values, the inverter
always cyclically sends new current values until the master formulates a new job.
When the device responds with 7:Job cannot be executed, the least significant
byte of the parameter value (PWE) (thus in byte 7) contains the applicable error
number.
