This normally high input signal will minimize power consumption by disabling internal circuitry and the output drivers when pulled low. If this is not your local representative, find your local sales rep here.

By simply inputting one pulse on the STEP input the motor will take one step full, half, quarter, or eighth depending on two logic inputs. There are no news items available for this product.

There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program. Click the image to view larger. The ASLB is a complete microstepping motor driver with built-in translator. This needs to be a 0V to 5V or 0V to 3.


Ce site contient essentiellement des notes de travail. This should be a 6V to 30V, 2A or more power supply that is clean low ripple. Connect the negative side of your power supply, as well as from any other boards you are using to drive the Easy Driver to one or more of the GND pins.

Each rising edge of this signal will cause one step or microstep to be taken. See below diagrams for how to hook these up. Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout UVLO and crossover-current protection.

The ASLB includes a fixed off-time current regulator that alleyro the ability to operate in slow, fast, or mixed current-decay modes. Connect this to the positive power supply lead.

A and B are the two coils of the motor, and can swap the two wires for a given coil it will just 367 the direction of the motor. The translator is the key to the easy implementation of the ASLB. Espaces de noms Page Discussion.


This one is complicated – please see the datasheet for more information.

These digital inputs control the microstepping mode. Allegto de navigation Outils personnels Se connecter. We default it to slow decay mode, but you can override with your own voltage on this pin. This is the power input to the Easy Driver. Special power-up sequencing is not required.

We’ll notify you when there are updates to this product. They are all connected together inside the board.

The tabs are at ground potential and need no insulation. Affichages Lire Voir le texte source Historique. This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced alkegro dissipation. This normally high input signal will reset the internal translator and disable all output drivers when pulled low.
