(1) Setting of axis to execute the speed change
The axis to execute the speed change set as (S1) sets J + axis No. in a character
sequence " ".

The number of axes which can set are only 1 axis.
Set "J" in a capital letter and use the axis No. set in the system setting as the axis
No. to start.
Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller Programming
Manual (COMMON)" for system settings.
