Interruption of sequence
Interruption by reset or emergency stop
When the started macro is interrupted by a reset or emergency stop before being completed, the abnormal
end signal (MCSP) becomes “1” and stops the execution of the program. Then, when the reset is
completed or the emergency stop is cleared, if the MEM mode is entered, the mode change request signal
(MCRQ) and the mode notification signal are output for mode recovery and the selection program is
recovered. (In a non-MEM mode, the system waits until the MEM mode is entered.) On the PMC side, be
sure to set the mode change completion signal (MCFIN) to “1” to complete the sequence, regardless of
whether mode recovery is made.
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.
Under such a condition, when reset or emergency stop are input, the operation which is described in
“Interruption by reset or emergency stop” is executed.
