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 Page 39, Section 1.2.3 for the stop cause.)
The "stop command processing for deceleration stop function" performs the following two operations:
• Deceleration curve re-processing
A deceleration curve is re-processed starting from the speed at stop cause occurrence to stop, according to
the preset deceleration time.
• Deceleration curve continuation
The current deceleration curve is continued after a stop cause has occurred.
This section explains the "stop command processing for deceleration stop function" as follows:
• Control details
• Control precautions
• Setting method
(1) Control details
The operation of "stop command processing for deceleration stop function" is explained below.
(a) Deceleration curve re-processing
A deceleration curve is re-processed starting from the speed at stop cause occurrence to 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.
