Description
The DDCS V4.1 3-4 axis motion controller is designed for stepper and servo systems. It is developed based on the DDCS V3.1 with updates in software and hardware. 
The controller adopts an ARM + FPGA architecture. The ARM processor manages the interface and G-code interpretation, while the FPGA executes motion algorithms and generates control pulses. The system operates on a Linux-based platform.
The DDCS V4.1 features a compact layout with 17 composite keys that function as both control and numeric keys. It supports a standard Fanuc-compatible G-code set. The unit can be panel-mounted into a control box or cabinet with four locking hooks.

Specification:
Panel Dimensions: 237 mm × 153.7 mm × 5.2 mm
Main Body: 237 mm × 153.7 mm × 48.2 mm
Mounting Cutout: 228.5 mm × 83.7 mm
