Question

PLC control stepper motor, how many can be controlled at most?

Comments

Hello everyone!   I make a piece of equipment, I expect to use 10-12 stepper motors, of which 8-10 are liquid pumps.

Our company's electrical engineer said that now we use the most PLC to control four motors, if the cost of adding modules is high, even if the PLC is used to communicate with each other, it takes three.

I want to ask everyone, is there a PLC from another manufacturer that can control the motor more, only control the motor, and there is nothing else about the cylinder.   If there is a lot of experience in this area, it is more enlightening

Answer 1

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 2

This is a schematic diagram of the structure that controls multiple stepper motors

Selection of controller model

Select the controller type and model from the following aspects:

1. Whether it can control multiple stepper motors;

2. Whether it can be mixed and controlled;

3. Whether it is suitable for use in control system occasions;

4. Is it easy and practical to use;

5. Whether you can master the programming technology of the control.

Select the meter-controlled controller, and check one by one as follows:

1. The meter control has 4 pulse output terminals, which can control up to 4 stepper motors or servo motors. There will be more pulse output terminals in the future. Currently, it can control 4 stepper motors to meet the requirements;

2. It can control various loads such as cylinder, hydraulic pressure, stepping motor, servo motor, etc. at the same time, and can realize the requirements of mixed control of various loads;

3. Considering that it only controls 4 stepping motors, the meter control can also control other loads with mixed control, and the anti-interference ability is also very strong. It is suitable for use in occasions with severe interference, and is used for control systems such as electric welding machines with severe interference. Work is also very stable.

4. Use table settings instead of programming, and use the mouse to set settings on the table according to the actual function requirements, which is relatively easy to use.

5. Whether you can master the use of meter control technology and programming technology is more important. The method of form setting is easier to master than programming, and form setting is simpler, more intuitive and easier to understand than traditional programming.
