the loaded regenerative energy to steadily and smoothly stop the motor in the fastest deceleration 
time.  
 4 (stall prevention by auto-acceleration and deceleration–reference to the acceleration and 
deceleration time settings): if the acceleration and deceleration time are within a reasonable range, 
the actual acceleration and deceleration time refer to Pr.01-12–01-19 settings. If the acceleration 
and deceleration time are too short, the actual acceleration and deceleration time are greater than 
the acceleration and deceleration time settings.

 Sets the time required to decelerate from the maximum operation frequency (Pr.01-00) to 0.00 
Hz through the CANopen control.
