Patent ID: 7960932

Claim:
A method for controlling an electrical door drive, comprising: determining a time profile of a drive torque of an electrical door drive during a reading-in process; deriving a maximum permissible torque for an opening process and a closing process from the determined time profile of the drive torque; comparing the maximum permissible torques with actual torques occurring during operation; switching off the door drive when the maximum torque is exceeded and/or a defined nominal closing rate of the door is undershot, because the door drive is obstructed, wherein pulse monitoring is carried out on the door drive over a time period for redundant obstruction identification, wherein, for the pulse monitoring of the door drive, a door drive motor is provided with an incremental transmitter which triggers a signal to switch off and/or to reverse the door drive motor on overshooting a defined time interval between the increments read in from the incremental transmitter encoder.
