Introduction

  • Series of ministep bipolar chopper drives, suitable for driving medium power two-phase stepping motors, with four, six or eight terminals.
  • Highly compact (70×70×25 mm), easy to use and cost effective solution. This system is designed to be soldered to a PCB.
  • Target: medium and medium-low power applications requiring increase in performance compared to self-built or integrated circuits combined with an improvement of reliability and durability.

Highlights

  • Microstepping function up to 3.200 step/rev.
  • Separated solder type connectors for logic signals and power connections.
  • Electronic damping facility for further acoustic noise and mechanic vibrations reduction at low and medium speed.
  • Standard input and output signals ease interfacing with the most commonly used control systems and ensure high noise immunity.

Technical Specifications

  • Version: open frame drive in 70 x 70 x 25 mm, equipped with connectors to be soldered on the PCB.
