Claim:
1. A fabric treating appliance for automatically treating a laundry load according to at least one cycle of operation, comprising: a rotatable treating chamber for receiving the laundry load for treatment; a motor for rotating the treating chamber; a speed sensor outputting a speed signal indicative of a rotational speed of the motor; a torque sensor outputting a torque signal indicative of a torque of the motor; a controller operably coupled to the motor and receiving the speed signal and torque signal, wherein the controller provides an acceleration signal to the motor to increase the rotational speed of the motor to accelerate the rotational speed of the treating chamber from a non-satellizing speed to a satellizing speed, and determines that the treating chamber has reached the satellizing speed by determining when a shape of at least a portion of the torque signal matches a corresponding portion of a reference torque signal, which is indicative of the torque when the laundry load is satellized; and wherein the controller provides the acceleration signal to the motor to increase the rotational speed of the motor at a predetermined rate.
