Auto-acceleration and Auto-deceleration Setting

Settings
 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.
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)
