8.3 Deceleration Check Method
(1)
Command deceleration check
After interpolation for one block has been completed, the completion of the command system deceleration is
confirmed before execution of the next block. The time required for the deceleration check is determined according
to the acceleration/deceleration mode and acceleration/deceleration time constant.
(a)
For linear acceleration/deceleration
(b)
For exponential acceleration/deceleration
(c)
For exponential acceleration and linear deceleration
The deceleration check time required during rapid traverse is the longest rapid traverse deceleration check time of
all axes. This check time is determined by the rapid traverse acceleration/deceleration mode and rapid traverse
acceleration/deceleration time constant of simultaneously commanded axes.
The deceleration check time required during cutting feed is determined in the same manner. It is the longest cutting
feed deceleration check time of all axes. This check time is determined by the cutting feed acceleration/deceleration
mode and cutting feed acceleration/deceleration time constant of simultaneously commanded axes.
