When the stepper motor is running, if there is obvious noise and vibration is caused to the stepper motor, the following steps is helpful to troubleshooting:
It really does matter whether the stepper motor is matched with the driver. If not, it may be useless to take following steps such as division, drive current and speed adjustment. It is suggested to buy a set and ensure it is qualified when selecting the stepper motor and driver.
Now the stepper motor driver is divided into digital and analog. The noise of the analog stepper motor driver is large while it is basically no for the digital one, generally because one DSP chip is added to the digital driver to optimize the stepper motor drive. Therefore, to ensure the noise and vibration is as small as it is, it is advised to use the digital stepper driver.
Correctly adjust the subdivision and current of the stepper motor driver. The larger the subdivision is, the smaller the change amplitude of coil in motor is. That is, the noise is mitigated. As for subdivision, it is advised to set it as 8 and above. Under the circumstance that there is enough torque to drive the load for the stepper motor, it is also necessary to reduce the driver current. The smaller the parameter set, the small the change amplitude of the coil in the motor is.
Correctly set the stepper motor’s acceleration and deceleration and highest rotational velocity. It is easy to generate additional noise during the acceleration and deceleration of the stepper motor. The solution is to increase the acceleration and deceleration of the stepper motor appropriately under the circumstance that acceleration and deceleration doesn’t cause losing step.
3. Why the stepper motor doesn’t rotate or move back and forth after it is powered?
If the stepper motor doesn’t rotate sometimes or move back and forth after starting, the following inspection for troubleshooting can be taken into considerations.
When selecting the stepper motor, considering whether the working torque is large enough and whether it can drive the load or not. Therefore, it is recommended to select the motor which has 30%-50% larger torque than the actual needs, because the stepper motor cannot rotate under overload, or causing losing step even if it overloads just one second. More seriously, the stalling or repeated and irregular motioning on the spot will be caused.
Check whether the input stroke pulse from the upper controller is correct, or whether the input frequency is high and maybe it is filtered by opt coupler.
Check whether the start frequency is too high and whether acceleration process is set in the start procedure. It is better to begin accelerating to the set rate from the start frequency regulated for the motor. No matter the acceleration time is very short, or it cannot be stable.
When the motor is not fixed, it is normal that such situation like the motor intense resonance may emerge sometimes. Therefore, the motor should be fixed.
Considering whether there is lack of phase. If so, the motor will vibrate and won’t rotate normally. As for 2-phase stepper motor, the motor also cannot work normally in case of wrong phase wiring.
