Advanced Motion Control Capabilities
The Turbo PMAC2 provides DSP-based closed-loop servo control with advanced algorithms such as PID with notch filters, acceleration feedforward, and friction compensation. It supports a wide range of feedback devices including incremental encoders, absolute encoders, resolvers, and SSI. The controller can execute coordinated multi-axis moves with linear, circular, and spline interpolation, making it ideal for complex path following.
USB and Ethernet Connectivity
The inclusion of USB and Ethernet ports greatly simplifies communication with the host system. The Ethernet interface supports TCP/IP, Modbus TCP, and EtherNet/IP protocols, allowing direct integration with PLCs and SCADA. The USB port enables fast firmware updates and high-speed data streaming for real-time monitoring and tuning. Additionally, a dedicated MACRO ring (fiber optic) provides distributed motion control over long distances with negligible latency.
Software and Programming Environment
The Turbo PMAC2 is programmed using Delta Tau’s PEWIN32 or PMAC-NC Pro software. The controller supports multiple programming languages: PMAC script (for motion and PLC tasks), G-code (for CNC applications), and standard C for custom libraries. The controller also includes a real-time operating system capable of executing background PLC programs in parallel with motion tasks.
Industrial Applications
CNC machining centers (milling, lathe, routers)
High-speed pick-and-place robots
Automated assembly and testing machines
Printing and converting machinery
Flight simulators and test stands
Conclusion
The Delta Tau Turbo PMAC2 CPU board with USB/Ethernet offers a powerful, real-time motion control solution for complex multi-axis applications. Its extensive I/O, networking options, and advanced interpolation capabilities make it a top choice for OEMs and system integrators.
