the reason the signal is not turned on.

762 SECOND SPINDLE MODE CHANGE FAULT
772 THIRD SPINDLE MODE CHANGE FAULT
782 FOURTH SPINDLE MODE CHANGE FAULT
These alarms are generated if the system does not properly
terminate a mode change. The modes include the Cs contouring,
spindle positioning, rigid tapping, and spindle control modes. The
alarm is activated if the spindle control unit does not respond
correctly to the mode change command issued by the NC.
The other alarms are the same as Cs contour axis when parameter CSS(No.3704#7)
is “0”. Refer to “FS16i/18i/21i CONNECTION MANUAL (FUNCTION) 9.9 Cs
CONTOUR CONTROL”.
6. NOTE
Note1 In the T series machines, the spindle contour control function and the spindle
positioning function cannot be used at the same time. If the spindle
positioning function is applied, set the parameter CSS (No.3704#7) is “0”.
Note2 In the spindle contour control mode, do not switch the spindle gears. When
the gears need to be changed put the system in the spindle speed control
mode first.
Note3 When this function is used in FS21i, PMC-SB7 is necessary.
