The following Figure shows the above-mentioned sequence.
- Interruption of sequence
Interruption by reset or emergency stop
The abnormal end signal (MCSP) becomes “1” when the operation is
interrupted by reset or emergency stop, and the execution of the
program is stopped. At this time, the mode change request signal
(MCRQ) and mode notification signal are output to recover the mode,
and the selection program number is recovered automatically.
Please set “1” in mode change completion signal (MCFIN) on the
PMC side to complete the sequence.
Feed hold or single block
The abnormal end signal (MCSP) is not output when stopping in feed
hold or single block. Under such a condition, when the cycle start
signal (ST) is turned on and off, the continuity of the macro program
is executed.
Under such a condition, even if macro call start signal (MCSTx) is
turned on and off, it is not effective.
