How many servo motors can a servo drive drive?

A servo drive.

A servo motor is driven separately.

is feasible without any problems.

If you want a servo drive to drive multiple Sevos, in principle, it is possible, but in practice it is not recommended.

1。Hardware connections. How drives can be connected to multiple SEVOs without interfering with each other.

Then you need to have a switching device, if the current drive is connected to a sevoWhen you're done, switch to B sevoSo what kind of equipment do you choose to completely connect the cable to device B, including the shielded cable, this is the biggest problem, and there is no guarantee of signal stability after switching, because of the direct hard-wire switching of the cable.

2.In terms of software, we can determine whether it is a device A or a device, and we can control the program to achieve immovable action, and the program implementation can be completed.

A servo motor refers to a servo system.

The engine that controls the operation of the mechanical components is an indirect transmission device of the auxiliary motor.

The servo motor can make the control speed, the position accuracy is very accurate, and the voltage signal can be converted into torque.

and rotational speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal, and can respond quickly in the automatic control system.

, which is used as an actuator and has a small electromechanical time constant and linearity.

High and starting voltage, etc., can convert the received electrical signal into angular displacement or angular velocity on the motor shaft.

Output. It is divided into two categories: DC and AC servo motors, and its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases uniformly with the increase of torque.

Only 1 unit can be brought.

Since the drive and motor together constitute a closed-loop system, to complete the so-called servo, the motor and the drive must be one-to-one.

The role of the drive has 2

1) According to the instruction of the upper controller (required speed), a certain driving current is generated to drive the motor to rotate.

2) According to the encoder to detect the actual speed of the motor (called feedback speed), and the upper computer command in 1) is carried out.

After comparison, adjust and change the driving current to make the motor speed reach the required speed of the upper controller.

If a driver has more than 2 encoders, the feedback speed of the encoders will be several values at the same time, so the driver will not know who to compare it with, and the whole system will become chaotic. The result is possible.

There are two. Either the drive burns out due to excessive driving current, or each motor is in its own array, and the eight immortals cross the sea and are in.

No (control) status.

Yes. The servo motor must be driven by a servo controller.

The servo motor and the servo drive are an organic whole, and the running performance of the servo motor is the comprehensive effect reflected by the cooperation of the motor and its driver.

One of the simplest servo control units is a servo motor plus a servo controller. It refers to the control of position, torque, speed or acceleration of a mechanical system through closed-loop control, and is the execution unit in the automatic control system, which converts the electrical signal of the upper controller into angular displacement or angular velocity output on the motor shaft.

The structure of the servo motor is basically the same as that of other motors, that is, there is an encoder to feedback the running status of the motor.

If you just want the motor to rotate, it's very simple to give the current, if you want to accurately control the position, speed, and torque, you need to make your own drive to calculate.

When you mentioned STM32 microcontroller, you want to use STM32 microcontroller as a driver, of course, this is okay, but you need to know the control algorithm of the servo motor first.

The control algorithm of each brand of servo motor is different:

1. Japanese brands are kept secret and can only be used with their drives.

2. Most of Europe and the United States are open, and you can develop your own drives.

1. Different control methods.

The speed control is analog control, and the position control is pulse control.

2. The adjustment speed is different.

In the speed control mode, the speed is adjusted with a voltage of 0-10, which is the analog key crack control mode.

3. The technology used is different.

These two control methods are implemented by two different control technologies.

This is different from open- and closed-loop systems for electromechanical systems.

A servo drive, also known as a "servo controller" and "servo amplifier", is a controller used to control a servo motor. Its function is similar to that of an inverter acting on an ordinary AC motor, which is part of the servo sock slag system and is mainly used for high-precision positioning systems.

Generally speaking, the servo closed motor is a transmission system that realizes high-precision positioning by position, speed and torque control, which is the high-end product of current transmission technology.

Servo drives and servo motors are the two main components of servo system reputation, each of which plays a different role.

Servo motor is the executive element in the servo system, it is a high-performance motor, compared with ordinary motors, servo motor has higher torque accuracy, lower inertia and faster response speed.

Servo motors are usually powered by three-phase AC power supply, and their speed, position, torque and other parameters can be accurately controlled by servo drives.

The servo drive is the controller in the servo system, which is responsible for converting the control signal into the control signal of the motor, and controlling the speed, position, torque and other parameters of the motor.

Servo drives, such as actuators, usually include signal acquisition, signal processing, power amplification and other modules, which can realize the precise control of the motor and ensure the stability and reliability of the system.

To put it simply, the relationship between a servo drive and a servo motor is: a servo drive is a controller, which is responsible for sending control signals and adjusting the parameters of the motor.

A servo motor is an actuator that receives these signals and generates corresponding actions based on them.

The two work together to allow the servo system to accurately control the position, orientation, status and other output controlled quantities of the object.

The average one can only be one. PLCs or frequency converters can drive multiple motors. Delta's ASDA-M series is a 3-in-1 type. It can do three-axis linkage, interpolation, etc.

Beijing Gende, Delta's largest first-class ** in North China.

Most of them are one!

Mitsubishi's new J4 servo can be equipped with 2 motors!

Generally, only one motor can be carried for one drive.

Some drives have a two-axis module, so it appears to be one drive with two motors.

It is basically not possible for a servo drive to control two servo motors. Because the servo amplifier and servo motor are 1-to-1 matching, unlike the inverter, you only need to choose a larger inverter to control the two motors.

Because the servo drive needs to be re-energized when the motor is replaced, the motor parameters are automatically identified and matched, and if the two motors are connected in parallel, the incorrect motor parameters and feedback signals will be identified, so the motor can not be well controlled, and even the alarm phenomenon will occur during operation!

It is even more impossible for two encoders to be connected in parallel, which will cause the pulse signals of the two encoders to interfere with each other, and it is estimated that an alarm will be given as soon as it is powered on!

Panasonic servo drive can be combined with the corresponding motor to form a servo system, which needs to be selected according to the corresponding current, rated power, speed, and encoder specifications.

The same signal output by a motion controller can control multiple drives and multiple servo motors to do synchronous actions.

I've tried, yes, just connect the 3 power cables of the motor in parallel, and the encoder wire of a motor can be connected without connecting it, but the driver power may not be enough.

At a glance at this problem, you will know that you are a novice, servo motor with servo drive first to know what encoder your servo drive supports, such as: increment, resolve, absolute value, and then see what protocol encoder your servo drive supports, if you don't understand, it is best to find a professional servo motor manufacturer to match you, such as Jerrett servo motor.

Remember that you can't take a Japanese servo with a European and American servo, for example, you can't take a Japanese servo motor with a European and American drive, it is recommended that it is best to buy which brand of servo motor with which brand of servo drive.

Finally, your question, can a three-phase 380V input driver drive a motor matched with a 220V driver? Or can a 220V input driver be used with a motor with a three-phase 380V input driver?

No, the 220V drive is equipped with a 220V motor, or the motor is easy to burn.
