Why do you go into the motor and you don't have to do it again
First, you check the connection again, the power supply, everything else is OK, Second (key) you check the breakdown Settings of your drive, current Settings, and pulse input methods. The frequency with which the controller is coming out is too high. According to the estimate of what you say is stepping motor drive is not set a good reason, my analysis is that maybe you just can be used, but you changed the driver in the running of one set, and then drive last Settings to take effect after restart, just your Settings are wrong
The electrical motor does not turn, and the hand swivel in the shaft to see if there is a lock, which is to see if there is any current input to the motor winding. Check if there is a problem with the connection, and you may not be able to catch it somewhere.
You see if the line is connected, I've seen this before, because it's not connected. Can you feel the motor vibrate with your hand? If you can! It could be that your drive pulse is too fast, and it's a step into the motor. Good luck to you!
Make sure that the above two points are not a problem, that is, the driver does not send the pulse to the motor, check the drive is normal.
?The step motor is an open loop controlling element which converts the electrical pulse signal into angular displacement or line displacement. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed point of view, called "step Angle", its rotation is based on the Angle of the fixed step by step. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment. Stepper motor is a kind of induction motor, its working principle is the use of electronic circuit, direct current (dc) into time-sharing power supply, multiphase sequential control current, in this current for stepper motor power supply, step motor to work properly, is time-sharing power supply for step motor drive, multiphase timing controller.
