Description

The CNC4X35A driver board is designed to operate bipolar stepper motors in full, half, quarter and eighth-step modes (configurable for each channel trough a dipswitch), with output drive capability of 35 V and up to 3.0A. This driver includes a fixed off-time current regulator that has the ability to operate in slow, fast or mixed-decay modes. This current decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.

Bipolar Chopper Drivers

Bipolar chopper drivers are by far the most widely used drivers for industrial applications. Although they are typically more expensive to design, they offer more performance and increased efficiency. Bipolar chopper drivers use an extra set of switching transistors to eliminate the need for two power sources. Additionally, these drivers use a four transistor bridge with re-circulating diodes and a sense resistor that maintains a feedback voltage proportional to the motor current. This kid of driver supply the correct current to the motor at all times.
