Four-axis motion support and versatile spindle control - 4-axis compatibility: enables four stepper motor drives or servo drives to be connected, supporting compact multi-axis configurations for CNC mills, routers, or other multi-axis systems. - High speed pulse capability: maximum step pulse frequency of 100 kHz, suitable for servo or stepper motors requiring precise, high-speed operation. - Analog spindle control: a 0-10V output port allows software-based control of spindle motor speed, reducing external hardware and enabling dynamic speed adjustments. - Flexible I/O: four general inputs to connect end switches, estop, probe switches, zero/home signals, and other devices for automation and safety. Applications and benefits - Ideal for 4-axis CNC setups where coordinated motion and spindle speed control are required, such as milling or routing with four axes. - Supports safe and automated operation through end stops, estop, and probing for quick homing and zeroing. - Suitable for educational labs, hobby workshops, and small production environments that need reliable multi-axis control with integrated spindle speed management. Use scenarios - Four-axis CNC milling or routing project that requires synchronized axis movement and programmable spindle speed. - Setup of a compact automation system with limit switches, emergency stop, and probing for accurate work offsets. - Educational or workshop bench to demonstrate multi-axis motion, spindle control, and basic safety interlocks.
