See below diagrams for how to hook these up. The ASLB is a complete microstepping motor driver with built-in translator. This normally high input signal will minimize power consumption by disabling internal circuitry and the output drivers when pulled low. The ASLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes.

This normally high input signal will reset the internal translator and disable all output drivers when pulled low. Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout UVLO and crossover-current protection.


Menu de navigation Outils personnels Se connecter. Special power-up sequencing is not required. We default it to slow decay mode, but you can override with your own voltage on this pin. This should be a 6V to 30V, 2A or more power supply that is clean low ripple.

By simply inputting one pulse on the STEP input allrgro motor will take one step full, half, quarter, or eighth depending on two logic inputs. Espaces de noms Page Discussion. Connect this to the positive power supply lead. We’ll notify you when there are updates to this product. There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program.

The translator is the key to the easy implementation of the ASLB. These digital inputs control the microstepping mode.

A and B are the two coils of the motor, and can swap the two wires for a given coil it will just 39667 the direction of the motor. This one is complicated – please see the datasheet for more information. They are all connected together inside the board. This needs to be a 0V to 5V or 0V to 3.

This current-decay control scheme results in reduced audible motor noise, increased allegro accuracy, and reduced power dissipation. 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.

The tabs are at ground potential and need no insulation. Each rising edge of this signal will cause alleyro step or microstep to be taken. Ce site contient essentiellement des notes de travail. This is the power input to the Easy Driver.
