• Data reading format
a. Communication request data from the computer to the inverter
c. Reply data from the inverter to the computer (No data error detected)
c. Reply data from the inverter to the computer (Data error detected)
e. Transmission data from the computer to the inverter when reading data
 Indicates a control code.
 Specifies the inverter station numbers in the range of H00 to H1F (stations 0 to 31) in hexadecimal.
 When Pr.123 or Pr.337 (Waiting time setting)  9999, create a communication request data without "waiting time" in the data format. (The
number of characters decreases by 1.)
 CR, LF code: When data is transmitted from the computer to the inverter, codes CR (carriage return) and LF (line feed) are automatically set at
the end of a data group on some computers. In this case, setting must be also made on the inverter according to the computer. Whether the CR
and LF codes will be present or absent can be selected using Pr.124 or Pr.341 (CR/LF selection).
