FCA65S sy Q01CPU I Q01CPU use the special instruction DDBA to modify the offset of G54 to G59 jobs. The screen display value has been changed, but when the workpiece is actually processed, the offset is still manually entered. "This setting is effective when data is re written and the next workpiece coordinates are changed by instruction," the instruction note said. But I don't understand what this sentence means. Can you help me to explain it?

FCA65S system, I use the special instruction DDBA to modify the offset of G54 to G59 jobs.

When the data is written, the new data does not take effect until the next G54 instruction. When new data is written, the G54 command must be added to the program before it becomes effective.

I have called G54. on the program, but the actual move position is the offset of the last manual input. Why。

Is not written completed, the results of the engineer's test is ok.
G54X0Y0;
Modify the G54 coordinates;
Re execute G54X0Y0 in the program,
The coordinates are changed to new ones.
