What happens when the step motor lock stops and stops?
Do you mean the motor shaft is locked when the motor stops? Disconnect the power supply? The step motor is like this, he has stopped the current, he assures the stepping motor to locate, and when the power supply is cut off, the current is not stopped.
Are the two motors the same? If it is the same, the drive to the motor will have another signal input, which will allow the motor to be unlocked when the input signal is entered. Not two signals are different.
This is a characteristic of the step motor, which is called the holding torque, which is the moment when the motor is connected to the motor but does not rotate, the stator holds the torque of the rotor. This is why there is no inertia for stepping motors.
