9.2.2 Switching from the virtual to real mode by operating system software

Switching from the virtual to real mode is executed by user side or operating system
software.
• By user side
• By operating system software ......... Switch automatically at the servo error detection.
(1) When the virtual to real mode switching is requested (M2043 ON
item in Table 9.4 is checked. If normal, it switches to the real mode.
(Confirm the check items in Table 9.4 for the switching from virtual to real mode,
and execute with all normal state.)
(
2) The real/virtual mode switching error detection flag (M2045) turns on at the error
detection, and the error code is stored in the real/virtual mode switching error
information storage register (D9193 to D9195). (Refer to APPENDIX 2.8)
Check item
• Are all axes (Virtual axis and real mode axis)
stopped? (M2001 to M2032 : OFF)
(1) If the following items are detected in the virtual mode operation, the operating
system software automatically switches back to the real mode.
• The forced stop is input.
• PLC ready flag (M2000) turns off.
• When "Return to Real Mode" is set as an operation on servo error, the servo
error detection signal (M2408+20n) turns on even if 1 axis.
(2) The error code is stored in the real/virtual mode switching error information
storage register (D9193 to D9195) at the switching back from virtual to real mode.
However, the real/virtual mode switching error detection flag (M2045) does not
turn on.
......... Turn the real/virtual mode switching request flag
(M2043) off.
