Stepping motor drive boxed NDC 94
( 24 - 75 VDC 0.6 - 2.0 Amp ) with Plug_in connectors

Introduction

► Series of ministep bipolar chopper drives, suitable for driving medium power two-phase stepping motors, with four, six or eight terminals.
► Compact, easy to use and cost effective solution. This system is designed for easy mounting inside a metallic electrical cabinet.
► Target: medium and medium-low power applications without special configuration requirement, but needing 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.
► Separated connectors for logic signals and power connections.
► Optoinsulated and differential input and output signals ease interfacing with the most commonly used control systems.

TECHNICAL SPECIFICATIONS

► Version: drive housed in a metallic box in 110 x 108 x 34 mm, equipped with plug-in connectors.
► Range of operating voltages: 24-75 VDC.
► Range of current: 0.6-2 Amps. Setting up to eight possible values by means of a dip-switch.
