Safe position monitoring ensures that the motor does not exceed a preset position limit value. If a limit value is violated, the motor is braked using a safe stop. The stopping performance achievable from a technical point of view must be taken into account. Below the limit value there are no restrictions in terms of acceleration or speed of the motor. Absolute position detection is required for this safety function. Absolute encoders may be used or relative measuring systems may be combined with a safe reference run.
