Ruida RDLC320-A (Co2 Laser DSP Controller for Laser Engraving and Cutting Machine)

The RDLC320-A laser engraving/cutting card is a controller developed by Ruida Technology for laser engraving/cutting applications. The hardware platform is based on the high-performance 32-bit floating-point processor DSP+FPGA architecture, which can complete large-scale and complex motion control algorithms, achieve continuous trajectory control and point control for multiple motion axes, and complete energy following control. The laser energy is uniform at any speed point. Large-scale logic gate array FPGAs can perform complex communication protocols and flexible IO extensions. USB communication is fast and easy to operate.

Description

Function description:

Advantages of the RDLC320-A laser engraving/cutting control card:

 

  • The board as a whole has better resistance to high voltage and anti-static interference;
  • Single 24V power supply (can also be powered by 36V power supply, but it is not recommended), which can save the cost of machine manufacturers;
  • Multi-channel universal high current IO, convenient for function expansion;
  • Support all brands, all capacity U disk, and the copy speed is 3 times that of the previous version system;
  • On-board 256M ultra-large capacity non-volatile memory, no longer has bottleneck restrictions on file size;
  • The system can self-check bad sectors and format the memory with good fault tolerance.
  • Two independent digital/analog power interfaces, the software can be separately adjusted to facilitate dual laser head control;
  • The motherboard program can be upgraded online to facilitate factory maintenance and customization of customer functions;
  • The boot screen can be upgraded online (customers can customize the boot screen and download it through the software);
  • The system comes with a time system (can display the year, month and day, the hardware encryption algorithm is more stable and reliable);
  • Support customer processing time preview (preview accuracy is 100%, preview time and actual processing time are accurate to milliseconds);
  • Support the backlash compensation function of the machine;
  • Added Z-axis linkage function;
  • Support for hardware limits;
  • Perfect power-off and continuous carving function;
  • Support system power-on reset is optional (ie, it can be reset or not reset);
  • Support multiple positioning point logic (you can set multiple positioning points to start work from different positioning points);
  • All manufacturers/user parameters can be backed up and restored (you can set a group of parameters to the factory default factory parameters on the panel, and also restore one-key of these default factory parameters);
