ABSTRACT:
A method for position and/or speed control of a linear drive utilizing a converter having a control unit and being coupled to a motor of the linear drive. The method includes determining, in a sensor-free manner, a motor position, generating a motor position signal, generating an acceleration signal utilizing an MEMS accelerometer provided in the control unit and arranged on a moving part of the linear drive, mathematically converting the motor position signal and the acceleration signal to a speed signal, and utilizing the speed signal to control the linear drive.
