 SM4A_SERV00-EE      Software kit for programming the drive with e3PLC Studio + 200 cm. serial cable with serial/USB converter

The SM4 line is a series of vectorial full digital drives with an integrated 50-poles motor, with local logic, programmable and equipped with PLC functionality. Suitable for use in 'stand alone' mode and connected to HMI touch screen for application parameters, these units have a serial interface (Modbus-RTU) for programming and debugging the application thanks to the eePLC Studio software environment which allows the user to access all the functions and resources of the device and to manage and synchronize the Movement Module and the resources of other drives with each process event. They also have ready-to-use and easily customizable modules such as: label management, cam management, cable processing, plate orientation, adjustment of printing registers and others.

Modbus is a communication protocol among the most widely used standards in the world of industrial devices. All our devices equipped with a serial interface (RS232 or RS485) implement and support the Modbus RTU protocol.

Ever Elettronica programmable drives represent something new: they integrate a real PLC on the drive to be able to create complex automations with a single device.

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.

Nowadays modern machines have to be flexible and adjustable to the production needs, quickly and easily. The use of the electric cam allows the reproduction of automatisms that, in the past, could only be obtained by a precise -but not very flexible- mechanical cams.
