Stepper motor drive PLUS E3

► Stepping motor drives series with Step & Direction interface suitable for driving two-phase stepping motors, with four, six or eight terminals . ► Optimized for driving R.T.A. EM series stepping motors with encoder (86 mm and 60 mm flange sizes). ► Target: applications requiring EM stepping motors. Control in a standard way (“OPEN LOOP”) but also give an alarm in case of loss of synchronism (“CLOSED LOOP”). ► Microstepping function up to 4.000 step/rev. ► Setting of the sensitivity of the loss of synchronism alarm system. ► 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. ► 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 Amp. Setting up to eight possible values by means of a dip-switch. ► Microstepping: 400, 800, 1.600, 3.200 and 500, 1.000, 2.000, 4.000 steps /revolution. Setting by means of dip-switches. ► Automatic current reduction at motor standstill. ► Protections: -Protection against under-voltage and over-voltage. -Protection against a short-circuit at motor outputs. -Overheating protection with thermal sensor. ► High efficiency CHOPPER with MOSFET final stage output. ► Electronic damping facility for further acoustic noise and mechanic vibrations reduction at low and medium speed ► Alarm memory by use of yellow blinking led. ► Warranty: 24 months.
