See Item (3) of this section.
CR Control code (Carriage Return) 1 byte CR (0x0D)
Note 12: The parameters that can be specified for reading are F002 to F004, A001 to A153, b001 to
b132, C001 to C159, H003 to H073, and P001 to P131. (To read the F001 parameter, use the
01 command.)

STX Control code (Start of TeXt) 1 byte STX (0x02)
Station No.
Station number of control-target
inverter
2 bytes 01 to 32
ACK Control code (acknowledgement) 1 byte ACK (0x06)
Data
Data to be sent (decimal ASCII
code)
8 bytes See Note 13.
BCC Block check code 2 bytes
XOR of the items from "Station No." to "Data."

Note 13: When the read parameter is an selection item, the Data part contains the code data
corresponding to the selection.
The code data corresponding to "H003" or "H203" (motor capacity selection) is as follows:
Code data 00 01 02 03 04 05 06 07 08 09 10
Japan or U.S.A. mode
(b085 = 00 or 02)
0.2 kW - 0.4 - 0.75 - 1.5 2.2 - 3.7 -
EU mode (b085 = 01) 0.2 kW 0.37 - 0.55 0.75 1.1 1.5 2.2 3.0 - 4.0
Code data 11 12 13 14 15 16 17 18 19 20 21
Japan or U.S.A. mode
(b085 = 00 or 02)
5.5 kW 7.5 11 15 18.5 22 30 37 45 55 75
EU mode (b085 = 01) 5.5 kW 7.5 11 15 18.5 22 30 37 45 55 75
For the value contained in the Data part when the read parameter is a numerical item, see the list of
function codes.
(Example) When the setting of the acceleration (1) time (F002) is 30.00 seconds, the Data part contains
"3000".
Negative response: See Item (2)-(ii) of this section.
