Check the cause of the abnormal operation of the stepper mot

Check the cause of the abnormal operation of the stepper motor:

1、the motor torque is large enough, can drive the load, so we generally recommend the user selection to choose the actual motor torque ratio to 50%~100%, because the stepper motor overload operation, even if it is instant, will cause serious loss, stop or irregular in situ repeated dynamic.

 

2、the host controller to input the current walking pulse is large enough (usually >10mA), so that the stability of optocoupler conduction, the input frequency is too high, resulting in not receiving, if the output circuit of the controller is the CMOS circuit, we must drive the CMOS input type.

 

3、The start frequency is too high, the acceleration process is set in the startup procedure, the best from the start frequency of the motor within the prescribed frequency setting began to accelerate, even if the acceleration time is very short, otherwise it may be unstable, even in idle state.
