Working principle:

pressing the power switch 271 causes the power switch 271 to close, the controller 24 detects whether the photoelectric switch 29 (initial sensor) is closed, and if the photoelectric switch 29 is detected to be closed, the controller 24 receives a corresponding signal and determines that the transmission assembly 22 is in the initial position, and an operator can mount a fitting (instrument); if the opening of the photoelectric switch 29 is detected, the controller 24 controls the motor 23 to move, so that the transmission assembly 22 moves backwards, for example, backwards by 5mm, and then moves forwards until the photoelectric switch 29 is triggered to be closed.

The controller 24 recognizes the type of the load 1 and invokes the motion parameters that match the load 1. The operator presses a button, the motor 23 is started, and when the movement stroke of the transmission assembly 22 reaches the limit, the controller 24 controls the motor 23 to stop rotating; when the motion stroke of the transmission assembly 22 is not limited, the motor 23 continues to move. The operator does not press a button and the motor 23 is stopped for waiting.

After the completion, the loading piece 1 is removed, and the power switch 271 is pressed to turn off the power switch 271.
