(2) Program Start Request Bit of Control Signal and Program Running Status Bit of Sta-
tus Flag
When the MP2000 system detects a status change in motion program control signal bit 0 (Program start request)
from OFF to ON, the motion program will start running. When the motion program successfully starts running,
status flag signal bit 0 (Program running) will turn ON. Status flag signal bit 0 (Program running) will turn OFF
when the END command in the motion program is executed.
To start the motion program again, turn motion program control signal bit 0 (Program start request) OFF, and
then turn it ON again.
Check the ON/OFF status of these signal by using the data trace function.
