## INTRODUCTION 

## HIGHLIGHTS 

- = Series of ministep bipolar chopper drives, suitable for driving medium power two ~~-~~ phase stepping motors, with four, six or eight terminals. 

   - = Microstepping function up to 4.000 step/rev. 

   - = Electronic damping facility for further acoustic noise and mechanic vibrations reduction at low and medium speed. 

- = Compact, easy to use and cost effective solution. This system is designed for easy mounting inside a metallic electrical cabinet. 

   - ™ Separated connectors for logic signals and power connections. 

- = Target: medium and medium ~~-l~~ ow power applications without special configuration requirement, but needing great dynamic performance, high reliability, low acoustic noise and mechanic vibrations reduction. 

- = Optoinsulated and differential input and output signals ease interfacing with the most commonly used control systems.
