Requirement analysis
Product Analysis
Key Points of the Requirement
Define the number of controlled axes, control modes (position, velocity, torque), and the fieldbus architecture (EtherCAT, CANopen, or pulse-direction). Specify the programming environment (IEC 61131-3, scripting interfaces, or ROS2 integration), integrated safety functions (STO, SS1, safe limited speed), handheld teach-pendant requirements, expansion I/O, and whether servo drives must be integrated into the cabinet or supplied separately. State the application—robot arm, AGV, or custom machine—and operating environment.
Cost Structure Analysis
Costs combine the main control board or industrial PC, power stages (whether drives are integrated), power supply and safety relay circuits, connectors and wiring, cabinet fabrication, and firmware licensing. Certification (CE, UL) and safety-function development are significant fixed costs amortized over volume. Integrated drive-controller products reduce cabinet wiring labor but concentrate heat, affecting enclosure cost.
Estimated Cost Range
Indicative factory pricing: single-axis servo drives $80–$400 each; standalone multi-axis motion controllers $300–$2,000; integrated robot control cabinets (controller plus multi-axis drives, without motors) $1,000–$5,000 depending on axis count and power. Quantities above 50–100 units typically negotiate 10–20% discounts. Final quotations depend on safety functions, certification scope, and software customization.
Procurement Considerations
Prioritize manufacturers who demonstrate fieldbus interoperability with your motors and sensors (request an integration test before mass order) and whose safety functions carry certification rather than self-declaration. Confirm SDK and API completeness, firmware update policy over the product lifecycle, and technical-support response commitments. Clarify cabinet interface drawings (connector pinouts, cable entry), spare-part availability, warranty terms, packaging, Incoterms, and delivery destination.
