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:

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.
