3 MOTION DEDICATED PLC INSTRUCTION
(3) Acceleration/deceleration time at speed change can be changed by setting the
acceleration/deceleration time change parameter of the axis specified with (S1).
Refer to the "Q173DSCPU/Q172DSCPU Motion controller (SV22) Programming
Manual (Advanced Synchronous Control)" for acceleration/deceleration time
change parameter.
Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller (SV13/SV22)
Programming Manual (REAL MODE)" for acceleration/deceleration time change
function.

[Setting range]
(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 " ".
(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.
