The SM4A line is a series of high performance and local logic vector drives suitable to be connected via CANbus (CANopen DS301/DS402), or serial (Modbus-RTU) to single or multi-axle systems in slave mode. Consisting of a Full Digital vectorial drive with "Else" firmware and a high torque 50-pole NEMA24 motor. Quickly configurable thanks to the interface for PC Windows SL-Monitor, these units are available in a wide range of powers. The SM4A series, as well as combining compactness and power, offers maximum versatility and reliability, allowing considerable savings in wiring and electrical panels. With the hardware resources available in the different versions, together with the implementation of the Advanced Power Motion Module, you can operate your application in a quick and easy manner.
