* If Data is a selection parameter value, the corresponding code data will be sent/received.
For example, the code data for the data set in the 1st/2nd Motor Capacity (H003/H203) are as follows.
• If Data is a numeric value, refer to the function code list.
Example. When the 1st Acceleration Time 1 (F002) is set to 30.00 s, Data is 3000.
