Stepper motor drive PLUS L5

motion controller

► Series of ministep bipolar chopper drives with an on-board programmable motion controller that can be used: - for the interfacing, through RS485 serial line, with a central control system - as an independent unit. ► Optimized for driving R.T.A. EM series stepping motors with encoder (86 mm and 60 mm flange sizes). ► Target: applications requiring a programmable motion controller and 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. ► Communication through RS485 serial line. ► Programmable motion controller allowing connection up to 48 drives on a single serial line. ► Setting of the sensitivity of the loss of synchronism alarm system. ► 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: 4.4-8 Amps. Setting up to four possible values by means of a serial line. ► Microstepping: 400, 500, 800, 1.000, 1.600, 2.000, 3.200 and 4.000 steps/revolution. Setting by means of a serial line. ► 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. ► Electronic damping facility for further acoustic noise and mechanic vibrations reduction. ► External fans not needed. ► Warranty: 24 months.
