Inverter → Computer

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.

1.2FH “/” (1 byte) ：Start code in binary mode

2.INV-NO (1Byte) ：Inverter number･･･00H to 3FH

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 judged invalid and no data will be returned.

Communication data will be invalidated and data will not be returned either if the in- verter number does not match. (Inverter number is considered matched if it is omitted during reception)

3. CMD(1Byte)	:‘Y’ (Block communication command [monitoring])
	Lowercase letter ‘y’ during an inverter trip, including standing by for retrying and during

atrip.

4.Number of read data groups (1 byte)

:Return the number of data groups to be read (00H to 05H).

5. Write status (1 byte) : Return 00H to 03H.

*Failing to write in the specified parameter in the number of write data groups, set “1” in the corresponding bit for the parameter failed to write. (See below.)

Bit Position	7	6	5		4	3	2	1	0
Data Type				－					

6.Read data1 - 5 (2 bytes)

:Return according to the number of read data groups. “0000H” is returned as dummy

data if “0” is selected as a parameter.

Read data1: Data selected by . Read data2: Data selected by .

Read data3: Data selected by . Read data4: Data selected by .

Read data5: Data selected by .

7.SUM(1Byte) : Checksum (Cannot be omitted) 00H to FFH

Lower two digits (1 byte) of total sum from start code of return data to read data.

Example

(When set as follows:  =  (Command information 1),  =  (frequency command),

 =  (status information), =  (output frequency),  =  (output current),  =  (output voltage) and  =  (alarm information)
