- Q: The failure of the step motor drive
- The LED is not bright Failure: the power supply is wrong; Low power supply voltage Solution: check the power connection. Boost voltage The motor does not turn, and the torque is not maintained Fault: the motor connection is not correct; Offline enable the RESET signal to be valid Solution: correct electrical wiring; Disable the RESET The motor doesn't turn, but it has torque Failure cause: no pulse input Solution: adjust pulse width and signal level The motor turns in the wrong direction Cause of failure: the power line sequence is wrong; The direction signal is wrong Solution: swap any two lines; Change direction setting Motor torque too small Cause of failure: the phase current is set too small; The acceleration is too fast; Motor blocked; The driver does not match the motor. Solution: set the phase current correctly; Decrease the acceleration; Eliminate mechanical failure; Change the appropriate driver.
- Q: How do the single-chip machine send pulse to the step motor drive? What's the pulse? The driver has a WC that receives the pulse!
- Need to see your stepper motor drives, have good stepper motor drive only need a thread to square wave pulse can drive the stepper motor rotation (and, of course, the positive and negative transfer control of a line and other lines) Some drives may require a few lines to encode (the code is in the specification) But generally the first kind is mostly, it is convenient to use
- Q: How does the servo motor drive work
- The power drive unit is the first through the three-phase full bridge rectifier circuit to the input three phase electricity or the municipal electricity to complete the rectifier, the corresponding direct current electricity. The three phase permanent magnet synchronous ac servo motor is driven by a three-phase sinusoidal PWM voltage inverter. The whole process of the power drive unit can be simply described as the ac-dc-ac process. The main topological circuit of the rectifier unit (ac-dc) is a three-phase fully bridge uncharged rectifier circuit.
- Q: How does the single-chip step motor drive connect
- The public is at the top of the > The pulse signal - - - >, a series of small resistors and a single chip output pulse The directional signal - - - > - a series of small resistance to a single chip With the above 3 lines can control the step motor moving, the electricity, the machine is automatically locked, if you still need to control stepping motor lock and release, the release signals to pick up a motor, connected with the pulse signal
- Q: How to learn more about stepping motors and stepping motors.
- When a motor is turned, the PWM subdivision drive is further studied. You can then learn about the drivers of various types of stepper motors, and the use of various types of drives. Then you can study how to reduce the vibration and noise of stepping motors. Then you can look at feedback control like PID.
- Q: How to set up the servo motor driver
- What brand are you using? There are many brands that are self-ordered.I hope my answer will help you
- Q: The voltage of the step motor driver?
- Input voltage affects the torque of stepping motor, the motor speed is proportional to the pulse frequency and startup if frequency is too high, stepping motor will not be able to spin, because the stator magnetic field changes too fast, the rotor can't keep up with, have to make the rotor has a acceleration process. Stop too, to have a slow process, do not suddenly stop pulse.
- Q: Can servo actuators control asynchronous motors?
- If it is to control the speed, torque accuracy is relatively high places there will be no ordinary motor, including electric spindle, you said the best way is to use servo motor. The main shaft is a high-speed motor, which is controlled by a transducer.
- Q: What is the principle of step motor drive?
- What are the advantages of drive segmentation? Why do you recommend using segmentation? The main advantages of drive segmentation are: eliminating the low frequency oscillation of the motor. Low frequency oscillation is a stepper motor (especially reactive motor) the inherent characteristics of the segment is the only way to eliminate it, if your stepper motor sometimes have to work in the resonance region (arc), select subdivision driver is the only option. The output torque of the motor is improved. In particular, the torque ratio of the three-phase reaction is about 30-40% higher than the non-break. Improved the resolution of the motor. By reducing the Angle of the step and increasing the evenness of the step distance, the "increase the resolution of the motor" is self-evident.
- Q: Why don't this step in the motor drive?
- The speed of the step motor is determined by the external control frequency and the segmentation, the first is to determine the subdivision, and to determine the control frequency.
