6.16  Deceleration Check

(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  : Acceleration/deceleration time constant

Td : Deceleration check time 

Td = Ts + (0 to 14ms)

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.
