RTA - HGD 05 - Open-Frame, Stepping Motor Drive

Stepping motor drive open-frame HGD 05
( 24 - 75 VDC 2.25 - 6.0 Amp )

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.
