Introduction

► Stepping motor drives series with Step & Direction interface suitable for driving two-phase stepping motors, with four, six or eight terminals based on the following versions:
-PLUS A3 and PLUS A4: with DC power supply (39-140 VDC)
-PLUS B3, PLUS B4 and PLUS B7: with AC power supply (28-100 VAC)
► Compact, easy to use and cost effective solution. This system is designed for mounting inside a metallic electrical cabinet. Suitable for wall mounting.
► Target: medium and medium-high power applications requiring great dynamic performance, high reliability, low acoustic noise and mechanic vibrations reduction.

HIGHLIGHTS

► Microstepping function up to 4.000 step/rev.
► Electronic damping facility for further acoustic noise and mechanic vibrations reduction at low and medium speed.
► External fans not needed: ideal both for mounting inside a metallic electrical cabinet and for stand-alone applications.
► Operation with built-in oscillator with speed range from 14 to 450 rpm setting by means of dip-switches.
