Stepper motor drive PLUS B3

► 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. ► 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. ► Version: drive housed in a metallic box 152 x 129 x 46 mm, equipped with plug-in connectors. ► Range of operating voltages: 28-62 VAC. ► Range of current: 2.4 - 8.0 Amp. Setting up to eight possible values by means of a dip-switch. ► Microstepping: 400, 500, 800, 1.000, 1.600, 2.000, 3.200 and 4.000 steps/revolution. Setting by means of a dip- switch. ► Automatic current reduction at motor standstill. ► Protections: -Protection against under-voltage and over-voltage. -Protection against a short-circuit at motor outputs. -Overtemperature protection with thermal sensor. ► Optoinsulated inputs compatible with differential control signals.
