What is meant by start/stop mode in stepper motors?
Slewing mode In start –stop mode the stepper motor always operate in synchronism and the motor can be started and stopped without using synchronism. In slewing mode the motor will be in synchronism, but it cannot be started or stopped without losing synchronism.
Why overshoots and oscillations are present in stepper motor response?
Stepper motors have discreet positions that the rotor can move to. Due to rotor inertia, when a stepper motor makes a step, it will overshoot its target slightly and oscillate before it gets the target point. Once the frequency matches motor natural frequency, oscillation will become resonance and causes noise.
Why does my stepper motor make high frequency noise?
Besides, please pull the power switch to on, currently, you are putting it on off. The motor may not get enough power to rotate. I only pull the “Power switch” to off, because i don`t want to damage the motor. The high frequency noise is only there, when the switch is to “on”.
What does it mean when stepper motor does not rotate?
There is a potentiomenter on the Megapi Stepper Motor Driver V1. When i adjust the potentiometer the sound changes from high frequency to low frequency; but the motor do not rotate. This potentiometer is for adjusting the current of stepping motor driver. The default position is on the middle, but you can turn it up or down.
Is the step motor noise a motion control problem?
Step motor noise, while annoying, is not a motion control problem in the sense that a mistake was made during the machine design process. Even if you doing everything right applying traditional control techniques, you will get some noise.
What does potentiometer on stepper motor do?
This potentiometer is for adjusting the current of stepping motor driver. The default position is on the middle, but you can turn it up or down. When potentiometer turned up, the chip will get hotter.
