Stop command processing for deceleration stop function

The "stop command processing for deceleration stop function" is provided to set the deceleration curve if a stop cause occurs
during deceleration stop processing (including automatic deceleration).
This function is valid for both trapezoidal and S-curve acceleration/deceleration processing methods.
Refer to the following for details of the stop cause.
Page 25 Stop process
The "stop command processing for deceleration stop function" performs the following two operations.
Control
The operation of "stop command processing for deceleration stop function" is explained below.
■Deceleration curve re-processing
A deceleration curve is re-processed starting from the speed at stop cause occurrence until at a stop, according to the preset
deceleration time.
If a stop cause occurs during automatic deceleration of position control, the deceleration stop processing stops as soon as the
target has reached the positioning address specified in the positioning data that is currently executed.

■Deceleration curve continuation
The current deceleration curve is continued after a stop cause has occurred.
If a stop cause occurs during automatic deceleration of position control, the deceleration stop processing may be complete
before the target has reached the positioning address specified in the positioning data that is currently executed.
