[Description]
Parameter data in the CNC can be read.
There are four types of parameters in the CNC: Bit parameters having a
definite meaning for each bit, byte parameters holding 1–byte data, word
parameters holding 2–byte data, and double word parameters holding
4–byte data. Therefore, the length of the read data varies according to the
parameter number specified.
Note that bit parameters cannot be read in bit units. The eighth bits (one
byte) for a parameter number must be read at a time.
For axis parameters (servo parameters), data for a specific axis can be
read, or data for all axes can be read at a time.

L = 1 : Reads bit or byte type parameter or pitch error compensation
value.
2 : Reads word type parameter.
4 : Reads 2 words type parameter.
When the servo parameter all axis is specified
L = 18 : Reads bit or byte type parameter.
28 : Reads word type parameter.
48 : Reads 2 words type parameter.
