The axis to execute the current value change set as (S1) sets J + Axis No. in a
character sequence " ".
(S1) usable range
Q173DSCPU 1 to 32
Q172DSCPU 1 to 16
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 command generation axis
parameter as the axis No. to start.
Refer to the "Q173DSCPU/Q172DSCPU Motion controller (SV22) Programming
Manual (Advanced Synchronous Control)" for command generation axis
parameter.
