4 POSITIONING DEDICATED SIGNALS
No.
1 PLC ready flag
2 Speed switching point specified flag
3 All axes servo ON command
4 Real/virtual mode switching request (SV22 only)

The data executed later becomes effective when the same device is executed in the Motion
SFC program and PLC program.
Explanation of the request register
Function
(Note-1) : The range of axis No.1 to 8 is valid in the Q172CPU(N).
(Note-2) : Device area of 9 axes or more is unusable in the Q172CPU(N).
(Note-3) : This signal is unusable in the SV22 real mode.
(Note-4) : Handling of D704 to D708 and D755 to D757 registers
Because cannot be turn ON/OFF for every bit from the PLC CPU, the above
bit devices are assigned to D register, and each bit device becomes on with
the lowest rank bit 0
with 1 0.
Use it when the above functions are requested from the PLC CPU using the
S(P).DDRD and S(P).DDWR instruction. Refer to the
"Q173CPU(N)/Q172CPU(N) Motion controller (SV13/SV22) Programming
Manual (Motion SFC)" for the S(P).DDRD and S(P).DDWR instruction.
The direct bit device ON/OFF is possible in the Motion SFC program.
(Note-5) : It can also be ordered the device of a remark column.
(Note-6) : M3080 does not turn off automatically. Turn it off as an user side.
