PUL+(+5V)

Pulse control signal: Pulse rising edge is effective;PUL-High power time4-5VLow level0-0.5V In order to reliably respond to impulse signals, the pulse width should be greater than2.5 Mu s If adopted+12Vor+24VSeries resistance is needed.

PUL-(PUL)

DIR+(+5V)

Directional signal: high/Low-level signal, in order to ensure the reliable commutation of the motor, the direction signal should precede the pulse signal at least.5 mu sSet up. The initial direction of operation of the motor is related to the connection of the motor, and any phase winding is exchanged (e.g.A+,A-Switching) can change the direction of the initial operation of the motor.DIR-High power time4-5VLow level0-0.5V

DIR-(DIR)

ENA+(+5V)

Enabling signal: When the signal is in high-level state, the driver makes the motor coil current flow through and locked; when the signal is in low-level state, the driver makes the motor current-free and relaxed. It is only useful in some special occasions. It is not used in general. It can be disconnected. The driver keeps the motor running as usual.
