3. 4.2 ENA port: enable/disable
When the default optocoupler is off, the drive outputs the current to the motor. When the internal optocoupler
is on, the drive will cut off the current of each phase of the motor so that the motor is in a free state, and the
stepper pulse can not be responded.
When the motor is in the wrong state, ，the drive can be restarted by ENA input。The existing fault should be
cleared at first. Then input a trailing edge signal to ENA terminal. After that, the drive can be excitation again
and running.
The level logic of the enable signal can be set to the opposite. The logic is opposite with above mentioned.
