29.2 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 required time for the deceleration check is equal to the longest
one of the deceleration check time for the simultaneously commanded axes, which are determined according to the
acceleration/deceleration mode and time constant.
(a) For linear acceleration/deceleration
Ts : Liner acceleration/deceleration time constant
Td : Deceleration check time Td = Ts + α(0 to 10ms)
(b) For exponential acceleration/deceleration
Ts : Exponential acceleration/deceleration time constant
Td : Deceleration check time Td = Ts×2 + α(0 to 10ms)
(c) For soft acceleration/deceleration
Ts : Soft acceleration/deceleration time constant
Td : Deceleration check time Td = Ts + α(0 to 10ms)
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.
