PROBLEM TO BE SOLVED: To set a value usable as the optimum threshold in the actual operation state. SOLUTION: In this thresholding, first of all, in the first step, a work adsorption device is actually operated continuously without a work, and a peak value in each cycle is determined, and the maximum value PA among them is stored (step S4). In the following second step, the work adsorption device is actually operated continuously with the work, and a peak value in each cycle is determined, and the minimum value PB among them is stored (step S8). Then, in the step 9, the threshold is calculated based on the maximum value PA without the work determined in the first step and the minimum value PB with the work determined in the second step, and the value is set as the threshold.
