Seek the speed regulation principle of stepping motor, the more detailed the better!
The stepper motor mainly according to certain rules for electrical, electrical signals to the corresponding response of the winding, the motor will run in a certain direction, and every change of electric motor will run a continuous step, if given in response to the electrical signal, the motor will run continuously, as long as the change of signal frequency, will gain speed different. If stepping motor speed regulation, as long as the frequency of the output pulse of the controller is changed, the speed regulation of the stepping motor can be realized. Some manufacturers have also introduced a stepper driver with internal pulse generator. Users only need to input analog electrical signals or speed through the potentiometer to realize stepper motors
You can operate the motor directly by sending digital tables, starting / stopping, searching for origin, or other digital input values from a PLC. The PLC may monitor the positioning completion signal from the driver, origin search, movement / stop, servo preparation, and other digital output signals
Sets the number and speed of pulses for the controller PLC. Example: Shan Tong and Shan Yang two-phase hybrid stepping motor as an example. It has a step angle of 1.8 degrees. You PLC send 200 pulses per second, turn a circle (without subdivision), you send 400 pulses a second, the motor will turn two times. The number of pulses, the speed, and the frequency are all controllable. If you hadn't studied PLC programming, you wouldn't have understood. If you know how to program. You can talk to me. Sanyo closed loop stepper system (we call it into the servo system -SANYO PB series Shanyang step) features: motor and AC servo motor and stepper system has the advantages of compact structure, high speed and high acceleration and deceleration operation can be carried out, no time to stop adjustment, excellent price, the most suitable for the visual system. Applicable to machine vision inspection equipment, label machine, liquid crystal manufacturing equipment, small engraving machine, robot, semiconductor processing device (binding, taping, sorting machine) Such as.1, SANYO, DENKI can be controlled by RS - 485 communication, also can controller (compatible with other brand controller), can also input instructions, driven by the drive. A pulse connection can control multiple axes. All movement parameters can be saved in the Flash ROM via the network settings. Provides a programming library (DLL) under the Windows 2000/XP system. 2, the position table is used for the motion control programming of the digital input and output signals of the main controller.
