: Valid
(Note-1): It is valid for the version (Refer to Section 1.4) that supports "synchronous encoder current
value monitor in real mode".
POINT
(1) It is unusable in the SV22 real mode.
(2) The range of axis No.1 to 8 is valid in the Q172DCPU(-S1).
(3) The device area more than 9 axes as a user device.
However, when the project of Q172DCPU(-S1) is replaced with Q173DSCPU/
Q172DSCPU/Q173DCPU(-S1), this area cannot be used.
