„Inverter → computer (binary mode)

At time of broadcast communication of the binary mode, returning of data is not executed except for the inverter to be returned (inverter number 00H) and when the inverter number is not matched. This is because there will be a risk that the returned data may be deformed.

•Data returned when data is processed normally (Binary mode) Omissible

(3.5bytes	“/”	INV-NO	CMD		Communication No.	DATA	SUM	(3.5bytes
Blank)	(2FH)	1 byte	1 byte		2 bytes	2 bytes	1 byte	Blank)
				Checksum area			Not omissible

1. 2FH (“/“) (1 byte) : Start code in binary mode

2.INV-NO (2 bytes) : Inverter number... 00H to 3FH (The inverter number is omitted if it is not found in the data received.)

If the inverter number matches up with that specified from the operation panel, data will be returned from the inverter. If the inverter number does not match, the data will be invalid and 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 on
	the command received.
	When the inverter is tripped...The lowercase letter 72H (r), 67H (g), 77H (w) or 70H (p) is
	returned 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 FFFFH
	The data read is returned for the 52H (R) and 47H (G) commands, while the data written is
	returned for the 57H (W) and 50H (P) commands.
6. Sum (1 bytes)	: Checksum (not omissible) 00H to FFH
	Value of the last two digits (1 byte) of the sum of a series of bits (codes) from the start code
	to the data.
