Optimal Acceleration/Deceleration Setting
Factory Setting: 0
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)
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.

Time Unit for Acceleration/Deceleration and S Curve
Factory Setting: 0
Settings 0: Unit 0.01 sec
1: Unit 0.1 sec
Time for CANopen Quick Stop
Factory Setting: 1.00/1.0
Settings
Pr. 01-45=0: 0.00~600.00 sec
Pr. 01-45=1: 0.0~6000.0 sec
It is used to set the time that decelerates from the max. operation frequency (Pr.01-00) to 0.00Hz
in CANopen control.
