When using the motor must pay attention to the problem?

Should you make before putting on electricity to run the following checks:1) the power supply voltage is appropriate (overvoltage is likely to cause the damage to the driver module);For input dc + / - polarity must not wrong,drive the motor model or current setting of the controller is appropriate (at the beginning of not too big);2) strong control signal lines,industrial site best shield to electricalmotor1.blogspot.com consider,such as using twisted pair);3) don't start in all of the need to connect the line,only together as the most basic system,after running well,and then gradually connection.4) must be clear grounding method,or is not empty.5) start running half an hour to closely observe the state of the motor,such as ac alternators 220vmovement is normal,voice and temperature rise,found the problem immediately stop adjustment.7,the stepper motor is up and running,sometimes move don't move or in situ to reverse,runtime sometimes out of step,what's the problem? 

Make check general to consider the following aspects:1) whether the motor torque is enough big,can drive the load,so we usually recommend the user selection to choose moment when 50%~100% larger than the actual need of motor,step motor cannot load running,even a moment,can cause 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 (> 10 generalnma),so that the optical coupling and stable conduction,the frequency of the input is too high,lead to receive less than,if the upper controller output circuit is CMOS circuit, Also want to choose CMOS input type of drives.3) whether the start frequency is too high,is set to accelerate the process in the launcher,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.gasoline generator spare parts4) when the motor is fixed,and sometimes this could be happening,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 A wrong motor cannot work.
