Patent ID: 8456111

Claim:
A linear drive configured to move at least one panel along a travel path, the linear drive comprising: at least one linear motor for the at least one panel, comprising: a stator member; a carriage; and a rotor member; a control circuit configured to: stop the at least one linear motor in the event of failure of an energy supply to the linear motor by switching-off the linear motor and operating the linear motor as a generator, enable displaceability of the at least one panel after stopping, perform a positioning run initially or after activation of the at least one panel to determine at least one limit stop of the at least one panel after the energy supply is applied, perform a learning run of the at least one panel to determine predetermined parameters for driving the at least one panel, the learning run including at least one displacement of the at least one panel in a first travel direction and at least one displacement of the at least one panel in a second direction opposite to the first direction, at a minimum travel speed, the control circuit comprising: a switch configured to switch off the energy supply of the at least one linear motor; and a microprocessor.
