Stepper motor stepper motor start running, sometimes move don't move or in situ to reverse, runtime sometimes out of step, what's the problem? 1)Motor torque is big enough, can drive the load, so we usually recommend the user selection to choose moment when 50% ~ 100% larger than the actual need of the motor, step motor cannot load running, even a moment, can create out of step, serious when a halt or irregular back again and again. 2)Host controller to input your step pulse current is big enough,General & gt; 10mA), so that the optical coupling and stable conduction, the frequency of the input is too high, lead to receive less than, if the host controller output circuit is a CMOS circuit, also should choose CMOS input type of drive. 3)Start frequency is too high, is set up in the launcher to accelerate the process, the best from the start of the motor regulation within the frequency began to accelerate to the set frequency, even if the acceleration time is very short, otherwise may be unstable, even in the idle state. 4)When the motor is fixed, sometimes this situation, belong to normal. Because, in fact, this caused the motor's strong resonance caused by the state of out of step. Motor must be fixed. 5)For 5 phase motor phase wrong, the motor can't work.
