15. PMC CONTROL FUNCTION
B–63523EN–1/03
1872
This function enables the following three operations in pushing the switch
installed in the machine only by the change in a minimum LADDER
program.
(1)Changes to MEM mode.
(2)Execution of macro program registered in memory.
(3)Return to the mode before macro program is executed.
And the program which had been selected before macro program is
executed is automatically selected.
This function is effective only in the reset state. That is, this function
cannot be used in cycle start state, feed hold state, and automatic operation
stop state.
The signal must be processed between PMC and CNC according to the
following procedures.
D Start
(1)The macro call start signal (MCSTx) is input from PMC to CNC
based on the signal from the macro call switch installed in the
machine.
D Mode change
(2)CNC outputs the mode notification signal and the mode change
request signal (MCRQ) when the macro call start signal (MCSTx)
is detected. At this time, MEM mode is notified as the mode
notification signal. The macro call executing signal (MCEXE) is
output at the same time.
(3)PMC must change the mode based on the signal output in the step
of above (2).
(4)Please set ”1” in the mode change completion signal (MCFIN) by
PMC when the mode change is completed. If the mode when
MCFIN signal is set to ”1” is different from the mode specified
from CNC in the step of (2), the alarm of P/S5306 is generated.
D Execution of macro program
(5)When MCFIN signal is set to ”1”, CNC executes the macro
program.
D End of macro program
(6)Please instruct M02 or M30 at the end of the macro program.
Moreover, please input external reset signal (ERS) or reset&rewind
signal (RRW) with M02 or M30 on the PMC side.
The program which had been selected before the macro is executed
is automatically selected by reset. The mode change request signal
(MCRQ) and mode notification signal are output at the same time.
At this time, the mode when macro call start signal (MCSTx) is
input is notified as the mode notification signal.
