9.8.3 Adaptive Control for Starting

In an adaptive control soft start, the soft starter adjusts the current to start the motor within a specified time and using a selected
acceleration profile.
The soft starter applies the current limit on all soft starts, including adaptive control. If the current limit is too low or the start
ramp time (set in parameter 2-2 Start Ramp Time) is too short, the motor may not start successfully.
