This normally high input signal will reset the internal translator and disable all output drivers when pulled low. They are all connected together inside the board.

There are no phase-sequence tables, high-frequency control lines, or complex interfaces to program. Affichages Lire Voir le texte source Historique.

There are no news items available for this product. This is allegto power input to the Easy Driver. 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. This one is complicated – please see the datasheet for more information. Each rising edge of this signal will cause one step or microstep to be taken.

We’ll notify you when there are updates to this product. Connect this to the positive power supply lead.

This current-decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation. The tabs are at ground potential and need no insulation.

A and B are the allegeo coils of the motor, and can swap the two wires for a given coil it will just reverse the direction of the motor.

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

The ASLB includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes. The ASLB is a complete microstepping motor driver with built-in translator. Special power-up sequencing is not required. If this is not your local representative, find your local sales rep here.

We default it to slow decay mode, 33967 you can override with your own voltage on this pin. 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.
