Abstract: In an embodiment, a method comprises: receiving, by a mechanical offset controller, input data; detecting, by the mechanical offset controller, a waveform command in the input data; responsive to the detecting, generating, by the mechanical offset controller, an unparking command; receiving, by a closed-loop controller, the unparking command; and moving, by the closed-loop controller, a mass in a haptic module from a mechanical resting position to a sensor reference position in accordance with the unparking command. The method further comprises: detecting, by the mechanical offset controller, that the input data does not include the waveform command; responsive to the detecting, generating, by the mechanical offset controller, a parking command; receiving, by a closed-loop controller, the parking command; and moving, by the closed-loop controller, the mass in the haptic module from the sensor reference position to the mechanical resting position in accordance with the parking command.
