Example 1: Reading a drive parameter (or data set)
To determine the parameter number and subindex for drive
parameter reading, multiply the parameter number by one
hundred and then convert it to hexadecimal. The low byte is the
subindex (IND), and the high byte is the parameter number (PNU).
For example reading parameter 84.11 INPUT 1 from the drive:
84.11 × 100 = 8411 = 20DBh.
Parameter number is 20 and subindex is DB.
