33 Deceleration Check
33.2 Deceleration Check Method
33.2 Deceleration Check Method
Command deceleration check method
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.
[For linear acceleration/deceleration]
Execution block
Ts: Liner acceleration/deceleration time constant
Td: Deceleration check time Td = Ts + α (0 to 10 ms)
[For exponential acceleration/deceleration]
Execution block
Ts
Ts: Exponential acceleration/deceleration time constant
Td: Deceleration check time Td = Ts × 2 + α (0 to 10 ms)
[For soft acceleration/deceleration]
Execution block
Ts: Soft acceleration/deceleration time constant
Td: Deceleration check time Td = Ts + α (0 to 10 ms)
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.
