①
After the CNC is turned on, when M05 output is valid, M03 or M04 is executed, M03 or M04
output is valid and remains, at the time, M05 output is closed; when M03 or M04 output is valid, M05
is executed, M03 or M04 is closed, M05 output is valid and remains; the spindle brake SPZD signal
output delay is set by No.087

, the hold time of the brake signal is set by No. 089

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
