Abstract
The present invention discloses a hand and press-button dual-way manual pulse generator with built-in indicator lamps, which comprises a rotation pulse input unit and a CPU. The CPU is connected with a forward rotation indicator lamp and an inverse rotation indicator lamp. The rotation signal input unit and/or the press-button signal input unit transmit the output signal to the CPU. The rotation pulse input unit transmits the output signal to the CPU where the output signal is processed and the control signal is then output through the difference chip. Meanwhile, the CPU collects control signals through the feedback circuit to realize self-check when the machine is turned on. The pulse generator has a non-contact structure extending significantly its service life than the prior art, which makes it durable. In addition, by installing a controller, built-in indicator lamps, and press-button control on the manual pulse generator, it offsets the technical defects of the current manual pulse generator, reduces the fault incidence, and greatly enhances work efficiency. Besides, the manual pulse generator has a simple structure that it is easy to manufacture and to widely spread in the field of the machine tool control.
