Stepper motor first let's explain what & other; Out-of-step & throughout; 。 Stepper motor is a pulse signal is converted to a displacement signal, is to give the motor a pulse, and turned a viewpoint. If the pulse frequency too fast, the motor can't scroll specified viewpoint, is equivalent to the meantime a few pulse signal lost, is lost, which is out of step. So how to detect stepper motor is out of step? Small make up in the han debao motor lists several ways can only let's test. Under normal circumstances three-phase stepper motor are points six took ten, five phase of the two. I wonder if we noticed three phase six controller are three LED, has taken five phase ten five leds? Three groups of three phase: motor winding, there would be three lines. Six pat: three leds, cycle twice came back to the starting conditions. Three phase three LED lights will shine every one, stepping motor will step into the 0. 1 silk, rotate the blink twice is 0. 6. Out of step motor are generally lack of the meantime a phase or two phase, that is to say, there is a line is broken,As to the motor or controller bad is about to check)。 This time we can make the motor step to fulfill, namely each step to 0. 1 silk, every step we use hand to shake the motor, to see if in certain conditions. If which LED light only when the motor without in determining the status which line has a problem, you can check it is related to the line. Turn off all the power, open machine and connected interface controller, find out the three lines, and then find out the 24 v power supply cord. Will play to electrical multimeter block, will be the three with a pair of 24 v line. Under normal conditions should be 8. About 5 ohm resistance, also some electrical resistance with intrusive, always which line if resistance with other wrong. The line may have a problem. If the testing results of the step motor aspects are right, it needs to use the same method to detect the controller problems. If there is a problem, as a result of the electrical machine go along you detect the line testing machine. If lucky, is the line is broken, it is ok to connect, unlucky words have to change the motor. If is the controller problem, also detected along the line always check up. You can see.
