ABSTRACT:
A process for the closed-loop control and thus for the limitation of the maximum allowable force on the primary and secondary closing edges of an automatic door. This object is achieved by conducting a verification of the drive system before each movement of the door panel. During this verification, the actual value of the motor current during the startup phase is verified by means of a stored motor torque characteristic.
