(Note-1): It can be used as the travel value change register. The travel value change register can be set to the device optionally in the servo
program. Refer to Section 6.15 for details.
POINT
(1) The following range is valid.
• Q172DSCPU : Axis No.1 to 16
• Q172DCPU(-S1) : Axis No.1 to 8
(2) The following device area can be used as a user device.
• Q172DSCPU : 17 axes or more
• Q172DCPU(-S1) : 9 axes or more
However, when the project of Q172DSCPU/Q172DCPU(-S1) is replaced with
Q173DSCPU/Q173DCPU(-S1), this area cannot be used as a user device.
