I saw a device without any sensors, and the servo can return to the origin very accurately. The servo is from Yaskawa, and the encoder is incremental. The servo motor rotates in a circular motion, sometimes it cannot rotate less than one turn, and once the action is completed, it returns to the origin. Sometimes it may take several rotations to ret...
2024-02-18263201、 Servo systemA servo system refers to an automatic control system that utilizes the action of a component (such as a control rod) to reach or approach a predetermined state, and can compare the desired state (desired value) with the actual state, adjusting the control components according to their differences (sometimes the rate of change of this...
2024-02-1826010The characteristics of servo drives1. The servo driver software program mainly includes the main program, interrupt service program, and data exchange program.2. The main program of the servo driver is mainly used to complete system initialization, LO interface control signals, and the setting of registers in various control modules within the DSP....
2024-02-0118910A frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's operating power supply. The frequency converter mainly consists of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, driving unit, detection un...
2024-02-0123510Stepper motors can achieve open-loop control of position and speed based on the number and frequency of pulses, making them an inexpensive, simple, and user-friendly control type of motor. They are increasingly widely used in the field of automation control. However, due to the fact that the stepper motor is not a closed-loop control, improper sele...
2024-01-3022110Is there a wiring method for servo motors that requires constant accuracy while following the rotor and rotating. If using a slip ring to connect the motor line and encoder line, will there be any out of step phenomenon? Is there any other better connection method.
2024-01-2621110Two sets of pulses are respectively connected to the same servo. One set of pulses controls the forward rotation of the motor, while the other set controls the reverse rotation of the motor. The two sets of pulses will not be triggered simultaneously. There is a program for servo pulse segments behind. The device is an old device that should have b...
2024-01-26236101. Why can't general motors be used in high-altitude areas?The altitude has adverse effects on motor temperature rise, motor corona (for high-voltage motors), and DC motor commutation. The following three aspects should be noted:(1) The higher the altitude, the greater the temperature rise of the motor, and the smaller the output power. Bu...

2023-12-2020710What is the sign for the servo to return to the origin? For example, there is a home button ->press the button ->the servo starts returning to the home point ->touch the home sensor (sensor closed) ->the servo starts decelerating ->the home sensor is disconnected (zero return completed)How to determine the completion of zeroing in t...
2023-11-2424010I remember to use a front and rear limit and a near origin for relative positions.Is it better to use absolute position or relative position for turntable servo? The turntable needs to be stuck once every time it passes through a workstation. What control method can be used to minimize the cumulative error as much as possible! And prevent the servo...
2023-11-2420110What is the reason why the laser motor autofocus is not ready？
2023-09-2822710The reason why the laser motor positioning and focusing are not ready is:1. The cooling capacity of the supporting cold water machine is insufficient. In winter, the contrast in cooling effect is not significant, but in summer, when the ambient temperature rises, it is impossible to effectively control the temperature of the cooling equipme...
