1. Dual output voltage of stepper motor driver

The stepper motor driver is a device that controls the forward and reverse rotation and incremental rotation of the stepper motor, and has multiple output modes. Among them, dual output is one of the common output modes. The so-called dual output means that the stepper motor driver drives two stepper motors at the same time. In the dual output mode, the stepper motor driver will have two output ports, which are used to drive two stepper motors respectively. The voltages of these two output ports can be set separately

2. Are the dual output voltages the same?

In theory, the dual output voltages of the stepper motor driver can be different. In other words, the voltage of each output port can be set independently. However, in practical applications, in order to ensure that the speed and accuracy of the two stepper motors are the same, the voltages of the two output ports are generally set to the same value.

The same voltage can ensure that the speed and accuracy of the two stepper motors remain consistent, thereby preventing the error phenomenon between the stepper motors. In addition, the same voltage can also facilitate operation and adjustment, reducing the difficulty of the debugging process.

3. The impact of different voltages on stepper motors

If the dual output voltages are set to different values, what impact will it have on the stepper motor? Generally speaking, it will affect the speed and accuracy of the stepper motor.

When the voltages of the two stepper motors are different, one of the motors will rotate slower than the other. This will cause errors between the stepper motors, making it impossible for the stepper motors to achieve synchronous rotation.

In addition, different voltages will also affect the accuracy of the stepper motor. If the voltage of a stepper motor is too high, it will produce a large angle error; if the voltage of a stepper motor is too low, it will leak steps, resulting in inaccurate position. These problems will affect the accuracy and stability of the stepper motor.

4. Summary

In general, the dual output voltages of the stepper motor driver can be different, but in practical applications, in order to ensure the speed and accuracy of the stepper motor, the voltages of the two output ports are generally set to the same value. Different voltages will affect the speed and accuracy of the stepper motor, thereby reducing the stability and accuracy of the stepper motor.
