*4 CR+LF code: When a computer transmits data to the inverter, some computers automatically provide either one or both of the codes CR (carriage
return) and LF (line feed) at the end of a data group. In this case, the same setting is required for data sent from the inverter to the computer. Use
Pr.124 or Pr.341 for the CR+LF code setting.
