Comprehensive Functional Safety Connectivity and Architecture
The certified Functional Safety connectivity options within the Titanium line are extensive, offering machine builders flexibility in implementing safety solutions tailored to their specific needs.
- Hardwired Safe Torque Off (STO): This fundamental safety function is universally recognized and provides a basic level of safety by reliably removing power from the motor, preventing unexpected startup or motion. STO is typically implemented via hardwired connections, ensuring a direct and immediate safety response.
- Configurable Safe I/O: The inclusion of configurable Safe I/O allows for direct integration of safety sensors (e.g., emergency stop buttons, light curtains, safety gates) and safety actuators into the drive’s safety architecture. This flexibility simplifies the design of safety circuits and allows for customized safety responses based on specific application requirements.
- FSoE Communication: As previously highlighted, FSoE enables safety-critical data exchange over the EtherCAT network. This is crucial for complex, distributed systems where multiple safety devices and drives need to communicate securely and reliably. FSoE significantly reduces wiring complexity, provides advanced diagnostic capabilities, and allows for dynamic reconfiguration of safety zones.
- Hybrid Architectures: The Titanium drives support hybrid safety architectures that combine the robustness of local hardwired safety functions with the flexibility and scalability of network-based FSoE communication. This approach allows designers to leverage the strengths of both methods, creating highly optimized and resilient safety systems that can adapt to varying operational demands.
Integrating these advanced safety functions directly into the servo drive offers numerous advantages. It significantly reduces the need for external safety components, such as dedicated safety relays or controllers, thereby lowering the Bill of Materials (BOM) and overall system cost. The reduction in external components and additional cabling also leads to a simpler system architecture, a smaller machine footprint, and faster assembly and commissioning times.
