Function

Description

PLS+

+ input Opto-isolated positive

Connect +5V power supply, work with +5V - +24V, limited resistor needed when higher than +5V.

PLS-

-  Pulse signal

Effects with falling edge, motor runs one step when input pulse change from low to high, input resistance is 220Ω, low level 0-0.5V, high level 4-5V, pulse width>2.5μs.

DIR+

+ input Opto-isolated positive

Connect +5V power supply, work with +5V - +24V, limited resistor needed when higher than +5V.

DIR-

- Direction signal

Used to change motor running direction, input resistance is 220Ω, low level 0-0.5V, high level 4-5V, pulse width>2.5μs.

ENA+

+ input Opto-isolated positive

Connect +5V power supply, work with +5V - +24V, limited resistor needed when higher than +5V.

ENA-

- Motor release signal

Low level, motor coil current cut off, driver stops work, and motor is not locked.
