Abstract
A start-up controller is programmed to continuously monitor the start-up acceleration of a motor using a stored acceleration profile to check the acceleration time against specification limits for the particular motor in which the controller is incorporated. The acceleration profile is an ordinal series of acceleration profile points in which each point is associated with a profile motor speed and a profile elapsed time. The controller terminates the acceleration of the motor if overall time elapsed since the start of acceleration is greater than the profile elapsed time associated with a profile point that is designated by the motor speed.
