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.
10-9-3 Emergency Stop
The emergency stop operation cancels the operating command immediately
and stops the active axis when the EMERGENCY STOP Bit turns ON in the
Axis Operating Output Memory Area.
When EMERGENCY STOP is executed, axis operation switches to position
control mode, and stops in Servo locked status. When EMERGENCY STOP is
executed during position control, the axis operation distributes the pulses
remaining in the Servo Drive's deviation counter and then stops.
EMERGENCY STOP can be executed for an axis that is servo-locked as long
as SERVO UNLOCK or DEVIATION COUNTER RESET is not being executed
and the command bits for these commands are not ON and as long as an axis
error has not occurred.
When executing EMERGENCY STOP, make sure that the EMERGENCY
STOP Bit remains ON until the Receiving Command Flag or Stop Execution
Flag in the Axis Operating Input Memory Area turns ON.
All axis operation commands except for SERVO UNLOCK and DEVIATION
COUNTER RESET will be ignored during EMERGENCY STOP execution or
while the EMERGENCY STOP Bit is ON.

Regardless of the previous control mode,
EMERGENCY STOP is executed after switching
to position control.
When pulses remain in the Servo Drive's deviation
counter, after EMERGENCY STOP is executed, the
remaining pulses are distributed and operation is
stopped.
The Servomotor is set to Servo lock status after
operation stops.
