Claim:
1. A laundry treating appliance for treating a laundry load according to at least one cycle of operation, comprising: a rotatable drum at least partially defining a treating chamber; a motor rotating the rotatable drum according to a motor control signal; and a controller operably coupled to the motor and providing a motor control signal to rotate the rotatable drum according to a speed profile for the at least one cycle of operation, with the speed profile including an acceleration phase where the speed of the rotatable drum is accelerated to a final speed, and the controller is configured to determine torque when the speed of the rotatable drum is periodically varied and the controller is configured to repeatedly determine inertia of the laundry load during the acceleration phase utilizing the determined torque, and configured to set the final speed based on the determined inertia.
