DS86 Digital Stepper Driver

Overview

The DS86 Digital Stepper Driver is a low-noise digital driver designed for stable and precise control of two-phase stepper motors. It uses a dedicated 32-bit DSP motor-control chip and advanced current control technology to provide smooth motor operation across low, medium, and high speeds.

The driver allows users to configure the motor current and microstepping according to application requirements. With adjustable current settings within a 0–6 A range and selectable microstepping from 1 to 256, the DS86 can accommodate a wide range of stepper motor applications.

The DS86 also incorporates automatic half-current operation, optically isolated differential signal inputs, and protection functions including over-current and over-voltage protection, making it suitable for various small- and medium-sized automation systems.
