Chapter 12 Description of Parameter SettingsC2000-HS
12.1-01-10
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-acceleration and auto-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 auto-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 auto-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 acceleration and
deceleration time settings.
Time Unit for Acceleration / Deceleration and S-Curve
