„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.

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
