4 POSITIONING DEDICATED SIGNALS
(10) Real mode/virtual mode switching status flag (M2044)
........................ Status signal
This flag checks the switching completion between the real mode and virtual
modes, and the current mode.
• This flag turns off with during the real mode or switching completion from the
virtual mode to real mode.
• This flag turns on with switching completion from the real mode to virtual
mode.
It can be used as an interlock for the servo program start or control change
(speed change, current value change).
(11) Real mode/virtual mode switching error detection flag (M2045)
........................ Status signal
This flag is used as judgement of the error available/not available at the mode
switching (between the real mode and virtual modes).
• This flag remains off if no error was detected at mode switching.
• This flag turns on if an error was detected at mode switching.
In this case, the error code is stored in the SD504.
(12) Out-of-sync warning flag (M2046) .............................. Status signal
(a) This signal turns on mode when a discrepancy of synchronized positions
between the drive module and output module occurs during the virtual
mode.
It is used as judgement for validity of the continuation operation when the
drive module has stopped.
• M2046 : ON...............Continuation operation disabled
• M2046 : OFF .............Continuation operation enabled
(b) This flag turns on the following cases.
• Stop by the forced stop.
• The servo error in the output module.
(c) When the out-of-sync warning flag turns on, resume operation by the
following procedure.
1) Return to the real mode and eliminate the error cause.
2) Synchronize the axes.
3) Turn the out-of-sync warning flag (M2046) off.
4) Switch to the virtual mode.
5) Resume operation.
