What do you mean by stepping into an electric motor?
The step motor drive signal EN is also called off-line signal When drive on electricity, stepper motor is locked when applying movement CP pulse (not) or running state when applying movement (CP pulse), but the user to manually adjust, but don't want to shut down the drive motor power? This is where the signal can be used. When this signal works (the general low level is valid), the motor is in free and no moment state; When this signal is high level or suspended, cancel the offline state. This signal user can choose, if not need this function, this end does not connect.
The driving power is to turn on the drive chip or the internal circuitry of the drive.It's kind of like a brake, and you need it to go away when you need it.
Does the motor release the signal? Normally the driver and the motor are connected, the electricity is connected, the electric current is between the driver and the motor, and the electrical opportunity is locked. If you need a motor to loosen, a signal will be sent to the driver and the motor will wiggle freely.
