6.16.2 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 time required for the deceleration check is determined according to the acceleration/ deceleration
mode and acceleration/deceleration time constant.
1) For linear acceleration/deceleration
Ts
Ts : Acceleration/deceleration time constant
Td : Deceleration check time
Td = Ts + (0 to 14ms)

Ts : Acceleration/deceleration time constant
Td : Deceleration check time
Td = 2 × Ts + (0 to 14ms)
3) For exponential acceleration and linear deceleration
2 × Ts

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 rapid traverse deceleration check time on 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.
