ζ is the distance the tool travels in 8 ms. It is 2000 in least
command increments when the feedrate is 15 m/min.

by parameters,
specify the data as the distance from the reference position in units of the
least command increment (output increment).
When setting the forbidden area X, Y, Z, I, J, K (X, Z, I, K, on T series)
by a G22 command, specify the data as the distance from the reference
position in units of the least input increment (input increment). The
programmed data are then converted into the numerical values in the least
command increment, and the values are set as the parameters.
Define the boundary with parameters Nos. 1324 and 1325. The area
inside the boundary becomes the forbidden area.
The parameter setting or programmed value (XZIK) depends on which
part of the tool or tool holder is checked for entering the forbidden area.
Confirm the checking position (the top of the tool or the tool chuck) before
programming the forbidden area.
If point C (The tip of the tool) is checked in Fig. 2.3.3 (g), the distance
“c” should be set as the data for the stored stroke check function. If point
D (The tool chuck) is checked, the distance “d” must be set.
