Embodiment 1

[0021] Embodiment one: see figure 1 As shown, a pull-up resistor module reverse voltage circuit board of a numerical control machine tool has a row of pull-up resistors 1 welded at one end and a row of diodes 2 welded at the other end.

[0022] A row of pull-up resistors 1 includes 8 resistors with a resistance value between 1KΩ and 10KΩ. The specific value of the resistance is obtained by calculating the relative current value of the chip. From the perspective of saving power consumption and the sinking current capability of the chip, the resistance should be large and the current should be small. In order to ensure sufficient driving current, the resistance should be small and the current should be large.

[0023] A row of diodes 2 is composed of 6 diodes welded on the reverse voltage circuit board of the pull-up resistor module in a specified direction, and releases the reverse voltage of devices such as solenoid valves of CNC machine tools.

[0024] The end where the pull...
