 3 (auto-acceleration and auto-deceleration–decelerating by the actual load): the drive auto-
detects the load torque and automatically accelerates from the fastest acceleration time and
smoothest start-up current to the setting frequency. During deceleration, the drive automatically
determines the loaded regenerative energy to steadily and smoothly stop the motor in the fastest
deceleration time.
 4 (stall prevention by auto-acceleration and deceleration–reference to the acceleration and
deceleration time settings): if the acceleration and deceleration time are within a reasonable
range, the actual acceleration and deceleration time refer to the Pr.01-12–01-19 settings. If the
acceleration and deceleration time are too short, the actual acceleration and deceleration time
are greater than the acceleration and deceleration time settings.
