Auto-acceleration and Auto-deceleration Setting 
 
 
  Default: 0 
  Settings  0: Linear acceleration and linear deceleration 
    1: Auto-acceleration and linear deceleration 
    2: Linear acceleration and auto-deceleration   
    3: Auto-acceleration and auto-deceleration 
    4: Stall prevention by auto-acceleration and auto-deceleration (limited by 
Pr.01-12 to Pr.01-21) 
 0 (linear acceleration and linear deceleration): the drive accelerates and decelerates according to 
the setting for Pr.01-12–01-19. 
 1 or 2 (auto/linear acceleration and auto/linear deceleration): the drive reduces the mechanical 
vibration  and  prevents  the  complicated  auto-tuning  processes.  It  does  not  stall  during 
acceleration and has no need for a brake resistor. It can also improve operation efficiency and 
save energy. 
 3 (auto-acceleration and deceleration-decelerate by actual load): the drive auto-detects the load 
torque  and  accelerates  from  the  fastest  acceleration  time  and  smoothest  start  current  to  the 
setting frequency. When decelerating, the drive auto-detects the load re-generation and stops the 
motor smoothly with the fastest deceleration time.   
 4 (stall prevention by auto-acceleration and deceleration –refer to acceleration and deceleration 
time): if the acceleration and deceleration is within a reasonable range, the drive accelerates and 
decelerates according to Pr.01-12–01-19. If the acceleration and deceleration time is too short, 
the actual acceleration and deceleration time are greater than the acceleration and deceleration 
time settings.
