② When M03（M04）output is valid, M04（M03）is executed, the alarm occurs.
③ When №175.6 is set to 1, the system checks whether the speed arrival signal SAR is
valid, if
it is valid, the system normally runs, if not, “Check speed arrival……” is displayed.
④ When the spindle speed command and the cutting feed command are in the same
block, the
system executes the delay check for SAR signal to avoid that the CNC starts the cutting
based on the
last spindle speed arrival signal SAR, the delay time is set by No.072.
⑤ DC00 is the spindle zero-speed output range. When the actual spindle speed is not
more
than DC00 setting value, the system defaults the spindle speed to be zero, and can
release the chuck,
close the hydraulic and other operations.
⑥ M20 and M21 are separate the spindle clamping and releasing command, used to
clamp the
spindle after positioning, which can avoid that the spindle rotates because of the force in
drilling or
tapping.
⑦ When M20 is executed, the spindle is clamped. To avoid that the spindle servo motor
has too
much current, the system delays the time set by DT23 and then controls the spindle to
turn off the
servo, at the time, the spindle servo reduces the motor excitation and the position control
cannot be
executed, but the position check is still enabled and the position is not lost.
⑧ When the spindle moves or rotates, M20(spindle clamped) cannot be executed. After
the
spindle is clamped, it cannot be rotated or moved, otherwise, the PLC alarms.
⑨ When K17.6 sets the spindle to be clamped, the clamped is the 1st or 2nd spindle, which
is set
based on the actual conditions.
⑩ SALM（X5.3）is the alarm input signal of the spindle abnormality, the signal and the
drive
alarm signal of the 5th axis use the same interface. When the 5th axis is valid, the interface
is used to
the 5th drive alarm; when the 5th axis is invalid, the interface is used to the spindle
