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.
