Optimal Acceleration/Deceleration Setting

Settings 0: Linear accel./decel.
1: Auto accel., linear decel.
2: Linear accel., auto decel.
3: Auto accel./decel. (auto calculate the accel./decel. time by actual load)
4: Stall prevention by auto accel./decel. (limited by 01-12 to 01-21)
Pr.01-44 is used to reduce the drive's vibration during load starts and stops. Also it will speed up to
the setting frequency with the fastest and smoothest start-up current when it detects small torque.
At deceleration, it will auto stop the drive with the fastest and the smoothest deceleration time when
the regenerated voltage of the load is detected.
Setting 0 Linear accel./decel.: it will accelerate/decelerate according to the setting of
Pr.01-12~01-19.
Setting to Auto accel./decel.: it can reduce the mechanical vibration and prevent the complicated
auto-tuning processes. It won't stall during acceleration and no need to use brake resistor. In
addition, it can improve the operation efficiency and save energy.
Setting 3 Auto accel./decel. (auto calculate the accel./decel. time by actual load): it can auto detect
the load torque and accelerate from the fastest acceleration time and smoothest start current to the
setting frequency. In the deceleration, it can auto detect the load re-generation and stop the motor
smoothly with the fastest decel. time.
Setting 4 Stall prevention by auto accel./decel. (limited by 01-12 to 01-21): if the
acceleration/deceleration is in the reasonable range, it will accelerate/decelerate by
Pr.01-12~01-19. If the accel./decel. time is too short, the actual accel./decel. time is greater than
the setting of accel./decel. time.
