When the instruction is executed by specifying "Jn" as Axis No., the complete status of
start accept flag is stored in the address of the start accept flag in the CPU shared
memory for target CPU.
The start accept flag for 32 axes are stored corresponding to each bit.
Bits are actually set as the following:
• Q173DSCPU/Q173DCPU(-S1) : J1 to J32
• Q172DSCPU
• Q172DCPU(-S1)
204H(516)
OFF: Start accept enable
205H(517)
ON : Start accept disable
The abnormal completion in the case shown below, and the error code is stored in the
device specified with the complete status storage device (D2).
If the complete status storage device (D2) is omitted, an error is not detected and
operation becomes "No operation".
Instruction request to Motion CPU from PLC CPU exceeds the permissible
value.
There are the following number or more simultaneous D(P).SVST/
D(P).CHGA/D(P).CHGAS
the PLC CPU, therefore the Motion CPU cannot process them.
• Q173DSCPU/Q172DSCPU
• Q173DCPU(-S1)/Q172DCPU(-S1) : 65 or more
Axis No. set by D(P).CHGA instruction is wrong.
