Description

Details

SMD258C Two-Phase Hybrid Stepper Motor Driver, Resolution up to 40000S/R

Overview

The SMD258C is a two-phase motor driver for hybrid stepper motors, supports 16 grades setting for both drive current and stepping subdivision, resolution up to 40000S/R. It is widely used in CNC equipment, sculpturing machine, cutting machine, etc.

Features

  • Wide range voltage input (DC 24V~80V)
  • 16 grades stepping subdivision setting, resolution up to 40000S/R
  • 16 grades drive current setting, adjustable between 0.5A/Phase and 5.0A/Phase
  • Supports three control modes: common cathode, common anode, and differential
  • Supports alerts for undervoltage, overvoltage, overheat, overcurrent
  • Supports phase memory when power down
  • Optical isolation for both I/O signal and input signal
  • When the stepping pulse stops over 100ms, coil current will be halved automatically
  • Comes with development resources and manual (examples for Raspberry Pi, STM32, Arduino)

Specifications

  • Operating voltage: DC 24V ~ 80V
  • Signal voltage: 4.2V ~ 24V
  • Drive current: 0.5A ~ 5A
  • Signal frequency: ≤150KHz
  • Control mode: common cathode, common anode, and differential

Applications

The SMD258C is suit for medium or small size CNC equipments which requires high resolution, such as:

  • Sculpturing machine
  • Glue dispenser
  • Automatic screw machine
  • Cutting machine
