(r) Servo OFF command (M3215+20n)
The servo OFF command is used to switch the servo OFF (free run status).
• M3215+20n: OFF..........Servo ON
• M3215+20n: ON............ Servo OFF (free run status)
This command is inoperative during positioning, and should therefore be
executed after positioning is completed.
When the servo OFF command occurs in the VIRTUAL mode, the clutch
will be disengaged before the servo OFF command is executed.
If the servo OFF command occurs while a "clutch ON" status exists, a minor
error will occur, and the servo OFF command will become inoperative.
(s) VIRTUAL mode continuation disabled warning(M3218+20n)
If, for an ABS axis, the difference between the final servo command value in
the last operation in the VIRTUAL mode and the servo current value the
next time a switch is made to the VIRTUAL mode exceeds the "POWER OF
ALLOWED TRAVELING POINTS (number of X feedback PULSES)" in the
system settings, a warning that VIRTUAL mode operation cannot be
continued is issued, and the "VIRTUAL mode continuation disabled warning
device" comes ON.
This is checked at the following times:
No. Check Time Remarks
