Answer 1

How many stepper motors can a stepper motor driver control?

In recent years, stepper motor driver technology has developed rapidly, it is an electronic device that can convert the input signal into the motion of the stepper motor, and can control the stepper motor to achieve precise position control. Stepper motor drivers can control multiple stepper motors to meet different application needs. So, how many stepper motors can a stepper motor driver control?

First, the stepper motor driver can control 2-8 stepper motors

Stepper motor drivers can control several stepper motors

The stepper motor driver is an electronic device that can precisely control the stepper motor, which can convert the input signal into the pulse of the stepper motor, thereby controlling the movement of the stepper motor. According to different models, stepper motor drivers can control 2-8 stepper motors, users can choose their own drive according to their own needs.

Second, the stepper motor driver can adjust the driving current according to demand

In addition, the stepper motor driver can also support various stepper motor parameter settings, changing the stepper motor speed, acceleration, torque and position control and other parameters to meet the needs of different applications.

Fourth, the stepper motor driver has high-precision position control

The stepper motor driver adopts a high-precision position control system, which can accurately control the rotation angle of the motor within a certain range, so as to achieve accurate position control. In addition, stepper motor drivers can also support a variety of position control modes, such as absolute position control mode, relative position control mode, and control step control mode, to meet the needs of different applications.

Fifth, the stepper motor driver has high safety

The stepper motor driver has high safety, it can detect the motion state of the stepper motor, and immediately stop the movement of the motor when an abnormal situation is found, avoiding dangerous situations, thereby improving safety performance. In addition, the stepper motor driver can also support thermal protection to immediately stop the motor movement when it detects that the stepper motor operating temperature exceeds the limit, thereby preventing the motor from overheating.

Sixth, the stepper motor driver has energy-saving function

The stepper motor driver has an energy-saving function, which can intelligently detect the load of the stepper motor and automatically adjust the size of the current, so as to achieve the purpose of energy saving. In addition, stepper motor drivers can support adaptive current regulation to maintain efficient motor operation even in harsh operating environments.

In summary, the stepper motor driver can control 2-8 stepper motors, support a variety of stepper motors, have high-precision position control, high safety and energy-saving functions, and is a very practical electronic device. In addition, stepper motor drivers can support a variety of stepper motor parameter settings to meet the needs of different applications. In addition, the programmable current control feature of the stepper motor driver makes it flexible to meet the needs of different application scenarios.

Answer 2

One drive controller controls 200 stepper motors, which is too much! The control of so many stepper motors is relatively rare, usually the control of several stepper motors, you can look at the table control TPC12-12TD type controller, can control 4 stepper motors and solenoid valves or other AC motors at the same time.

Answer 3

The general multi-axis controller on the market can control multiple step axes and control them with pulses, but generally there are no more than 64 axes, let alone 200 axes linkage. 

If you can, I think you can try to do some solutions, the complex part with multiple controllers for local control, the simple part with pulse control can be realized.

Answer 4

How can a drive-in motor control two step-in motors at the same time?

Recently, a customer asked whether a stepper motor driver can be equipped with 2 stepper motors at the same time, and the answer given by Adecco Intelligent Control is: Yes.

There are two options for one drive with two step-in motors:

　　1. Time-sharing work

2. Work synchronously

The stepper motor is divided into two or more working stages, and it is necessary to share a stepper motor driver, and the stepper motor of the stepper motor can be configured according to needs, and the action of the stepper motor is switched separately through the relay.

However, this scheme has two disadvantages, one is the loss of accuracy, and the other is that the stepper motor will lose phase during the relay switching process, especially repeated switching will cause cumulative error. And after the switch, it is in the enabled state, which may lose position on the device. Another disadvantage is that it is easy to damage, and if the relay is damaged, or the program is wrong, it can damage the stepper motor drive and even the power supply.

Step into the drive

Stepper motors need to share a drive, two or more stepper motors work synchronously, first of all, the maximum output current of the stepper motor driver is greater than or equal to the sum of the rated currents of several stepper motors. Second, when the stepper motor is started and stopped synchronously, due to the high reverse electromotive force, it will have a certain impact on the drive, resulting in a shortened life of the drive in this application state. Our company has equipped customers with laser cutting machines, precisely because there are two motors that work exactly the same.

Therefore, Adecco Intelligent Control manufacturers recommend that the stepper motor corresponds to the supporting stepper motor driver.

Answer 5

Often when engineers select stepper motors, they will ask how many stepper motors can you carry in one drive?

Theoretically, a drive can carry several stepper motors, and the practical application is divided into two situations, time-sharing work and synchronous work.

Two or more motors work in time, can share a stepper motor drive, the power selection of the stepper drive and the drive power supply can be configured according to the requirements of a stepper motor, and the separate actions of the two stepper motors are switched by relay.

However, this scheme has two disadvantages, one is the loss of accuracy, the phase of the stepper motor will be lost in the process of relay switching, especially repeated switching will lead to cumulative error. Moreover, it is in the enabled state after the switch, and may lose its position on the device. Another disadvantage is that it is easy to damage, if the relay is damaged, or the program is wrong, it can lead to damage to the stepper motor drive and even the power supply.

Two or more stepper motors work synchronously and can share a drive, first of all, the maximum output current of the stepper motor driver is greater than or equal to the sum of the rated currents of several stepper motors. Secondly, because the reverse electromotive force is high when the stepper motor is started and stopped synchronously, it will cause a certain impact on the drive, resulting in a shortened service life of the drive in this application state.

In order to have absolute control over the stepper motor and facilitate debugging, we usually use a stepper motor with a drive. In order to further save customer procurement costs, Kaifu Technology successfully developed the one-to-two stepper motor driver Y2SDD1R5 series, which can work in speed mode and pulse direction mode or double pulse mode, and the operating current and speed segment or subdivision parameters can be set through the switch, which greatly facilitates the customer's application.

One tow two stepper motor driver adopts I/O (speed mode) or pulse (pulse mode) control stepper motor driver, through market verification, superior performance, with high-speed large distance output, low noise, low vibration, low heat and other characteristics, if you have any questions, you can contact online customer service email.

Answer 6

Can multiple stepper motors be controlled with one drive?

When choosing a stepper motor, we generally choose a matching stepper motor driver together. Tuoda electrical engineers generally recommend customers a stepper motor equipped with a drive. In some special applications, one drive can also drive two or more stepper motors at the same time, but in order to ensure the stability of the equipment drive structure. A stepper motor paired with a stepper motor driver is a good solution.

Answer 7

The drive mechanism of a stepper motor can be divided into two parts: a ring distributor and a power amplifier.

Cycle distributor: can receive 3 signals separately: pulse signal, direction signal, offline signal. The pulse signal is then distributed to control the transistor path corresponding to the power amplifier, so that the stepper motor coil can obtain electrical energy. As shown in the figure, the stepper motor must input pulse when running, if there is no pulse, the stepper motor will not move, therefore, we need a drive for the windings of various stepper motors to start sequentially.

Directional signal: control the phase sequence of AB energized, AB clockwise, B-A counterclockwise;

Offline signal: when the stepper motor stops, the AB coil has a phase of electricity, the function of the power is to lock the rotor, so that the rotor can not move, when it is necessary to collect the rotor, you need to give the offline signal, so that the AB phase winding is completely offline, the rotor rotates freely.
