Analysis of common fault codes of stepper motors

A stepper motor is an electric motor that continuously rotates at a fixed angle to drive the equipment to work. Its rotation angle is closely related to the number of electron pulses. The working principle of a stepper motor is to control a set of electromagnets to rotate the rotor into position. However, how to prevent failures when using stepper motors?

When the stepper motor fails, the system will issue a prompt code, and we can use these codes to determine the specific problem. Common fault codes are as follows:

• 0001: The stepper motor is not working properly.
• 0011: The stepper motor rotates too fast.
• 0010: The stepper motor speed is insufficient.
• 1010: The stepper motor vibrates excessively, causing excessive noise.

For these fault code problems, we conduct cause analysis and solutions from four aspects.

First of all, for the fault code (0001) that occurs when the stepper motor cannot work normally, the possible cause is that the motor is damaged or the electromagnet drive circuit is faulty. If this fault code appears, you should first check whether the drive circuit is operating normally. If you can't find the problem, you can consider replacing the motor.

Secondly, when the fault code (0011) of excessive speed occurs, it is most likely caused by a short circuit in the solder joint of the drive circuit or poor wiring. If this is the case, you need to recheck the wiring to make sure it is connected correctly and not loose. If there is a problem with the welding, it will need to be re-soldered.

For the fault code of insufficient speed (0010), more care and patience are required. This situation is often caused by the motor being overloaded, the power supply voltage being unstable, or even the drive circuit having problems. In order to solve this problem, it is recommended that we use a low-voltage, high-torque motor, maintain the power supply voltage, or make circuit adjustments.

Finally, when the stepper motor has a fault code (1010) due to excessive vibration and excessive noise, the best solution is to improve the working efficiency of the correction reactor and increase the quality of the motor. At the same time, we can also consider changing the design of the drive circuit to alleviate this situation.

These are just some solutions for specific situations, and actual situations vary. Each fault code requires detailed analysis, and you need to find out where the problem is in order to solve the problem correctly and quickly.
