Stop Functions
Section 10-9
First-step deceleration curve operations require parameter settings for Pn80E
only. For the acceleration/deceleration curve, Pn810 and Pn811 must be set
when using an exponential curve, and Pn812 must be set when using an
S-curve.
The SMARTSTEP Junior Servo Drives do not support the following parame-
ters: Pn80D and Pn80F. They also do not support acceleration/deceleration
filters, so the filters cannot be set. A one-step linear deceleration curve is set
using only Pn80E.

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.
