DESCRIPTION PLUS L is the name of a sries of ministep bipolar chopper drives intended for driving R.T.A. EM sries stepping motors with encoder (86 mm and 60 mm flange sizes). They are equipped with an on-board programmable motion controller that can be used: - for the interfacing with a central control system (through RS485 s驩riai line) - as an independent unit. PLUS L sries drives can control EM stepping motors in a standard way ("OPEN LOOP"), but also give an alarm in case of loss of syncronism ("CLOSED LOOP"). PLUS L sries drives are housed in a metallic box, 152 x 129 x 46 mm format, suitable for wall mounting. They do not need external fans: accordingly, they are id驩al both for mounting inside a metallic electrical cabinet and for stand-alone applications. m Motion Control Systems
