The SM4 line is a series of vectorial full digital drives with an integrated 50-poles motor and an encoder, 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, also in Closed-loop, 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.

  1. • Control mode
  2. • Velocity control mode
  3. • Different positioning Control Modes (homing, relative, absolute, target)
  4. • Electric Gear with programmable gear ratio to track external master reference (from fieldbus or incremental encoder) of motor Speed and Position
  5. • High speed I/O triggered motor start & stop to event syncronizing for fast response demanding application: labeling, nick_finder, on fly cut., etc...
  6. • Multi Axis movements syncronization capability
  7. •On fly change among any Motion Module Control Modes
  8. •On fly Electric Gear Enable/Disable capability
  9. • Control of the drives by commands from the Master Controller. Suitable for Multi-Axis Systems (up to 127 drives). Integrates all the features of the Power Motion Module that ensures perfect synchronization between the axes and reduces the workload of the Master Controller
  10. • Programming and debugging of the drive through Service SCI. For this purpose, the SM4A_SERV00-EE soft-start kit is available, including converters and cables from service serial to RS485 and from RS485 to USB. The kit is accompanied by a CD-Rom with eePLC Studio IDE software in the demo version
