Stepping Motor driver can control pulse signal band through single chip Microcomputer
The stepper motor driver can control the pulse signal through a single chip Microcomputer. A friend asked me a question. Suppose we use the pulse signal method of a single chip microcomputer control panel, then pass it to the stepper motor driver. Can you drive 2 stepper motors at the same time? Then I will solve this problem.
At the same time, I also want to make these two non-stepping motors rotate at the same angle. Is it OK? In fact, there are two solutions to solve this problem.
First of all, we should solve the problem of stepping motor driver, stepping motor, and the choice of power supply. This is a more complicated matter, but we can save money for stepping motor driver, the budget can also not be reduced.
There is also a better consideration in terms of safety, that is, we only refer to whether this single chip microcomputer can drive two stepping motor drivers at the same time, and whether the driving capability is enough. Suppose we don't look at this manual, usually, if a stepper motor driver needs 30MA current, it is absolutely safe.
If we look at the first one, you will find that it can be but it always feels Unreliable. If we drive two stepping motors at the same time, then the machinery driven by the stepping motor is different, the parameters set will also be different, so that there will be mutual interference. If you want to use it, I suggest you use the second method here, because the result is the same, it is to increase the torque and accuracy, so this is better, safer and more reliable.
