In the cases below, the inverter ignores a query and returns no response.
•When receiving a broadcasting query

•When the slave address set in the query is not equal to the slave address of the inverter
•When a time interval between data elements constituting a message is shorter than 3.5 characters

NOTE: Provide a timer in the master and make the master retransmit the same query
when no response is made within a preset time period after the preceding query was sent. AppendixB
