The Stop Execution Flag turns ON when DECELERATION STOP or EMER-
GENCY STOP is received, but does not check whether the remaining pulses
in the Servo Drive are within the positioning completion range, unlike the PCU
Positioning Completed Flag in direct operation.
The Stop Execution Flag turns OFF when direct operation, jogging, speed
commands or other movement commands are executed.
10-9-4 Stop Function Timing Chart
The following timing chart is for when DECELERATION STOP is executed.
The timing chart for EMERGENCY STOP is the same, except that operation is
stopped after distributing the pulses remaining in the Servo Drive.
When DECELERATION STOP or EMERGENCY STOP is executed during
direct operation (ABSOLUTE MOVEMENT/RELATIVE MOVEMENT) or ORI-
GIN SEARCH, the PCU Positioning Completed Flag will not turn ON when
operation stops. Even if the stop position for DECELERATION STOP/EMER-
GENCY STOP is within the positioning completion range of the target position
for the initial positioning operation, the PCU Positioning Completed Flag will
not turn ON.
