- Q:Which triode will be chosen for this step motor driven circuit?
- PLC working voltage is 24 v, optical coupling circuit can need not change, in front of triode can use 8050. Light coupling output side, 10 k resistor can be appropriate in a bit, current-limiting resistance in a bit of light. The triode in the back consists of the darlington form. The model depends on the power of the motor you are driving. Power small words can be used in 8050, large words can be used D882. Or using integrated drive ULN2003 and so on.
- Q:What is the difference between the speed control mode of servo drive and the position control mode?
- Speed control is analog quantity control, position control is pulse control. The speed control mode USES 0-10 voltage to adjust the speed, which is the analog quantity control mode. The one that your teacher says is pulse control regardless of speed or position, it's just in position control mode. The velocity is the frequency of your pulse, the number of pulses that you send out. Does that make sense?
- Q:What happened to the motor that was controlled by the step motor drive
- There is no direction signal, and the 5V power supply goes through a 1K resistor to the DRI +, the negative electrode of the DRI. DRI - and DRI + power are in one direction, and power cuts are in the other direction.
- Q:Step forward motor single pulse/double pulse?
- The motor is in the circuit with the letter "G". Its main function is to use mechanical energy to convert into electricity, and the most commonly used is to use heat energy and water energy to push the rotor of the generator to generate electricity.
- Q:How the servo driver works
- Servo drives, servo drives) is also known as "servo controller" and "servo amplifier, a controller is used to control the servo motor, its action is similar to the frequency converter to ordinary ac motor, belong to the part of the servo system, mainly used in high precision positioning system. Typically by location, speed and torque three ways to control the servo motor, high precision positioning of transmission system, is currently the transmission technology of high-end products. Working principle: The current mainstream servo drive adopts digital signal processor (DSP) as the control core, can realize more complex control algorithm, realize digitization, networking and intelligence. Power devices are widely used in intelligent power module (IPM) as the core design of drive circuit, IPM internal integrated drive circuit, at the same time has the overvoltage, overcurrent, overheating, under-voltage protection circuit, such as fault detection in the primary loop to join the soft start circuit, to reduce the impact to drive during startup. 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 do you measure the output current of the step motor driver
- A series of current in one phase of the continuous running of the machine can be seen in one phase In the phase line, the resistance of a single one in the phase line is used to see the waveform on both ends of the resistance, and the maximum on the oscilloscope is the peak current
- Q:What is the communication servo motor driver and how it works
- Permanent magnet ac servo motor Since the 1980 s, with the integrated circuit, power electronic technology and the development of ac variable speed drive technology, permanent magnet ac servo drive technology has the prominent development, all countries well-known electrical manufacturers have launched their own ac servo motor and servo drive series products and constantly improve and update. The ac servo system has become the main development direction of the modern high performance servo system, so that the original dc servo system faces the crisis of elimination. Since the 1990s, the world's commoditized ac servo system has been powered by a full-digital sine wave motor. The ac servo actuator is developing rapidly in the field of transmission. Comparing with dc servo motor, the main advantages are: There is no brush and commutator, so the work is reliable and requires low maintenance and maintenance. It is convenient to heat the heat of the stator winding. The inertia is small and easy to improve the speed of the system. It is adapted to the high speed torque. There is a smaller volume and weight under the same power.
- Q:Can servo actuators control asynchronous motors?
- Can't, Ac servo motor is also a brushless motor. It is divided into synchronous and asynchronous motors The inside of the servo motor rotor is a permanent magnets, three-phase electric drive control of U/V/W form the electromagnetic field, under the action of rotating rotor in this field, at the same time, motor with encoder feedback signal to drive, drive according to the feedback value compared with the target, adjust the Angle of the rotor rotation. The accuracy of the servo motor is determined by the accuracy of the encoder (line count).
- Q:How is the single chip machine controlled
- Using a dedicated drive circuit like UN2003, such as the darlington array or L298N, you can also build your own H bridge.
- Q:What does the servo drive encoder line number 2500ppr mean
- Servo drives, servo drives) is also known as "servo controller and the servo amplifier, a controller is used to control the servo motor, its action is similar to the frequency converter to ordinary ac motor, belong to the part of the servo system, mainly used in high precision positioning system. Typically by location, speed and torque three ways to control the servo motor, high precision positioning of transmission system, is currently the transmission technology of high-end products.
