I am debugging a stepper motor, just start the line can work properly, but after power failure again on the power will not turn, how do not turn, the amount of motor coil resistance is normal. Please expert guidance and guidance!
The stepping motor is an open loop control element which transforms the electric pulse signal into angular displacement or linear displacement. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle, called "step", it is the rotation of the fixed point of the operation step by step. We can control the angular displacement by controlling the number of pulses, so as to achieve the purpose of accurate positioning. At the same time, we can control the speed and acceleration of motor rotation by controlling the pulse frequency, so as to achieve the purpose of speed regulation.
First, you check the connection again, the power supply, and so on, and the rest are OK's.,Second (focus) you check your drive's subdivision settings, current settings, and pulse input mode, whether or not it is set correctly. And the frequency that the controller sends out is too high?.According to estimates of what you say is why the stepper motor driver is not set, my analysis is the case, you may just be used in the operation, but you modify a setting of the drive, and then restart the driver after the final set to take effect, just your settings are incorrect.
Stepper motor is an induction motor, its working principle is the use of electronic circuit, the DC power supply variable components, multi-phase timing control current this current stepper motor power supply, stepper motor can work normally, the power supply for the stepper motor driver is divided into the multi phase sequence controller.
Reason：1, the electric motor does not turn, hand rotating stepper motor shaft to see whether it has been locked, that is, to see whether the current input to the motor winding.2, check the connection is no problem, maybe some place is not connected.3, to confirm the above two points no problem, that is, the driver does not send a pulse to the motor, check the drive is normal
