E658131511 Inverter → computer (binary mode)At time of broadcast communication of the binary mode, returning of data is not executed except forthe inverter to be returned (inverter number 00H) and when the inverter number is not matched. Thisis because there will be a risk that the returned data may be deformed.• Data returned when data is processed normally (Binary mode)Omissible(3.5bytesBlank)“/”(2FH)INV-NO1 byteCMD1 byteCommunication No.2 bytesDATA2 bytesSUM1 byte(3.5bytesBlank)Checksum area Not omissible1. 2FH (“/“) (1 byte) : Start code in binary mode2. INV-NO (2 bytes) : Inverter number... 00H to 3FH (The inverter number is omitted if it is not found in the datareceived.)If the inverter number matches up with that specified from the operation panel, data will bereturned from the inverter. If the inverter number does not match, the data will be invalidand no data will be returned.3. CMD (1 byte) : Command...The command is also used for a check when the inverter is tripped.Under normal conditions...52H (R), 47H (G), 57H (W) or 50H (P) is returned, depending onthe command received.When the inverter is tripped...The lowercase letter 72H (r), 67H (g), 77H (w) or 70H (p) isreturned with 20H added to it, depending on the command received.4. Communication No. (4 bytes): The communication number received is returned.5. Data (2 bytes) : Data ... 0000H to FFFFHThe data read is returned for the 52H (R) and 47H (G) commands, while the data written isreturned for the 57H (W) and 50H (P) commands.6. Sum (1 bytes) : Checksum (not omissible) 00H to FFHValue of the last two digits (1 byte) of the sum of a series of bits (codes) from the start codeto the data.
