<p>The drive has a drive arrangement with two electrical drive motors (10, 20) and an electrical controller with an electronic control unit, all supplied from the electrical supply network and/or an electrical energy storage arrangement, especially an accumulator. Door panels (1, 2) can be driven by one motor in one state and by the other motor in another state, or each panel can be driven by a separate motor in one state and by one motor in a second state. Alternatively, in one state the panels can be driven by several coupled motors in one state and by only some of the motors in the other state, in which some of the motors, which are not driving the panels, are switched off.</p> |
