Example: Read the ACC parameter
The following example on how to read the value of the ACC registers is
presented. The guidelines in the example are as follows:

Unit address is 2 (S11 = 2, S12 = 0)

The actual value of ACC in the drive is 10,000 decimal / 0x2710

From the table, the address of ACC is 2 and the data type is long.

As defined in above text, all variables are 32 bit constructed with 2 contiguous 16
bit registers.
Transmit the request to read the value of ACC:
0x02
0x03
