Description
High / low level state, requirements: low level 0~0.5V,
high level 4~5V, corresponding to two directions of the
motor. The initial running direction of the motor
depends on the motor wiring; swap any phase to
change the initial running direction of the motor.
Rising edge active; each time pulse signal changes from
low to high, the motor moves one step; requirements:
low level 0~0.5V, high level 4~5V, pulse width ≥1.5us.
Used to enable/release motor, EN+ connects to +5V,
EN‐ is grounded, the drive will cut off electrical current
of each phase in a free state, and the temperature rise
and heating of the drive and motor will be reduced.
When this feature is not in use, keep the signal terminal
null.
