Embodiment Construction
[0026] As shown in Figure 1, the electronic cam controller is composed of a button display circuit, a DSP main control chip, an I / O interface circuit, an encoder input interface circuit, an encoder output interface circuit, and a power supply circuit. The button display circuit is used to display crankshaft angle and speed, production count, braking distance, alarm prompt and other information as well as user input parameters. The encoder signal is sent to the DSP main control chip through the encoder input circuit, which is convenient for the program processing of the DSP chip, and outputs the cam signal, clutch brake signal, etc. The I / O signal of the machine tool is sent to the DSP main control chip through the I / O interface circuit, and it is also the channel for the output of the cam signal. The power supply circuit supplies the required voltage to the controller. Among them, the DSP main control chip stores the control program to realize the control of the press.
