Description

technical field [0001] The invention belongs to the field of generation and control of square wave pulse signals, in particular to a multifunctional manual generation and control device for stepping and servo-driven square wave pulse signals. Background technique [0002] A square wave pulse signal is a pulse signal that appears at regular intervals according to a periodic frequency, and is widely used in control devices involving stepper and servo drive motors. The square wave pulse signal controls the phase sequence of the current applied to the motor by controlling the electronic devices inside the driver, thereby generating a force in one direction and making the motor rotate continuously, thereby controlling some stepper motors, servo motors and some DC motors. The square wave pulse signal control motor has many advantages: high reliability of motor control, less prone to speeding accidents, strong signal anti-interference ability, etc. [0003] Among existing devices ...

AI Technical Summary

Problems solved by technology

Based on the generation and control of square wave pulse signals by single-chip microcomputers, the requirements for users are relatively high, and they need to understand some underlying knowledge such as circuits and programs, especially anti-interference knowledge. In industrial field control, square wave pulse signals composed of single-chip microcomputers are directly used. It is difficult to guarantee the reliability, stability and availability of ground generation and control devices

Based on the PLC generation and control of square wave pulse signals, the hardware systems of various manufacturers are incompatible with each other. When a PLC product is selected, the corresponding control procedure must be selected. The controller composed of PLC has relatively large volume and quality. , inconvenient to operate in field control

In the generation and control of pulse signals based on an independent pulse generator, its function is relatively single, and the on-site real-time control is poor, which cannot meet the current needs in the field of square wave pulse signal generation and control.
