Method for monitoring functional state of screw, involves stopping failure occurred in motor function, when slope of detected drive torque is lower than predetermined threshold value
Method for monitoring functional state of screw, involves stopping failure occurred in motor function, when slope of detected drive torque is lower than predetermined threshold value
The method involves detecting the drive torque, when the driving operation of screw is stopped. The failure occurred in motor function is stopped, when the slope of detected drive torque is lower than a predetermined threshold value. An independent claim is included for computing unit.
