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 vector 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.

CANopen is a standard communication protocol widely used in the industrial automation fields. First developed for use with CAN fieldbus, it has also been applied to other types of fieldbuses such as Ethercat CoE.

Thanks to the ELSE technology integrated in the Ever Elettronica’s drives motors current control is so high that vibrations, resonances and noises don’t exist anymore.

The innovative f4d2 technology allows the motor’s excitation at high efficiency chopper thanks to the calculations speed for the current regulation performed by the drive's microprocessor and thanks to a proprietary patented algorithm.
