Abstract
Provided herewith is an improved scheme for parking a load such as an indicator pointer and calibrating its position in a system for controlling the position of the load. The system also has a stopper for physically impeding the load when it is to be parked. In one embodiment, a parking method involves driving the motor in a reduced torque mode to move the load toward the stopper, stopping the load at the stopper while the motor is driven in the reduced torque mode, and maintaining the motor in a reduced torque mode until transitioning to an insignificant torque mode.
