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.)

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
Japan or U.S.A. mode
(b085 = 00 or 02)
EU mode (b085 = 01)
Code data
Japan or U.S.A. mode
(b085 = 00 or 02)
EU mode (b085 = 01)
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.
