9 REAL MODE/VIRTUAL MODE SWITCHING AND STOP/RE-START

9.4 Stop and Re-start

The basic method for stopping the system (output module) in the virtual mode
operation is to stop the main shaft. If an auxiliary input axis is used, also stop the
auxiliary input axis.
(1) Virtual axis stop
The stop operation or causes of virtual axis, the stop processing and re-start after
stop are shown below. The following three methods for the virtual servomotor
axis stop processing. This processing is also valid for interpolation axes during
the interpolation operation.
• Deceleration stop ..... Deceleration stop based on the "stop deceleration time"
• Rapid stop ................ Deceleration stop based on the "rapid stop deceleration
• Immediate stop ....... Immediate stop without deceleration.
Because the synchronous encoder axis becomes the input immediate stop,
operation should be executed after the synchronous encoder axis has been
stopped from the external input, except for abnormal stops such as the forced
stop or a servo error occurrence, etc.
(Example : M2000 is OFF, All axes servo OFF command, etc.)
(The servo error occurs by the immediate stop of output module connected to the
synchronous encoder axis, and the synchronization discrepancy may occurs.)
When the synchronization discrepancy occurs by the stop cause, the
synchronization discrepancy warning (M2046) turns on. In this case, re-align the
axes in the real mode, turn M2046 off, then continue the virtual mode operation.
The stop operation/stop causes during operation and re-starting operation after
stop are shown in the next page.
