MLA-SIC Linear module with stepper motor with built-in controller + RS485

Linear module with stepper motor and built-in motion controller with the possibility of programming and control via the RS485 bus MODBUS-RTU.

The controller makes it possible to determine any trajectory of the carriage movement and the implementation of motion programs programmed by the user.

The controller also has universal inputs and outputs that allow the module to respond to external events or control external devices.

The SIC-CONFIGURATOR application is available for programming / configuring the device, which, through the USB interface, allows you to easily configure the parameters of the module operation and test the traffic parameters. Additional ML-PROG software allows you to create motion programs for the module to work independently.

Integrated controller properties:

  • Programmed trajectory of movement (position, speed, acceleration)
  • Memory up to 300 motion commands
  • Universal inputs and outputs
  • RS485 MODBUS-RTU interface allowing the control of multiple modules at the same time
  • USB connector for configuring / programming the module
  • Intuitive software in Polish

The controller can work with the following types of engines:
