Main Features and Advantages
Precision Motion Control for Legacy Systems: The SIEMENS 1FT5076-0AC01-2-Z is specifically engineered to interface with SIMODRIVE 611 A analog drive platforms, providing ±10V analog command compatibility that is essential for retrofitting and maintaining older CNC systems. Unlike newer digital servo motors such as the 1FT6 or 1FK7 series, the SIEMENS 1FT5076-0AC01-2-Z communicates through traditional analog signals and feedback loops, making it the only direct replacement option for systems like Siemens 840C, 810M, and early 810D controllers. This unique compatibility ensures that facilities operating legacy machine tools can maintain their production equipment without costly full-system upgrades.
High Torque Density and Overload Capability: The SIEMENS 1FT5076-0AC01-2-Z delivers a continuous rated torque of 22 Nm at 2000 RPM, with peak torque capabilities reaching approximately 58 Nm during heavy cutting operations. This robust torque performance ensures reliable feed drive operation for heavy machining applications, including milling, turning, and grinding processes. The SIEMENS 1FT5076-0AC01-2-Z operates with Class F insulation and S1 continuous duty rating, guaranteeing sustained performance under full-load conditions in three-shift industrial environments.
Integrated Feedback for Closed-Loop Precision: The SIEMENS 1FT5076-0AC01-2-Z features a comprehensive feedback package including a tachogenerator for velocity feedback and an incremental encoder for position verification, enabling precise closed-loop control essential for micro-level positioning accuracy. The encoder resolution, typically 2048 pulses per revolution, ensures the SIEMENS 1FT5076-0AC01-2-Z can maintain position accuracy within microns, critical for achieving high-quality surface finishes and dimensional tolerances in CNC machining. The integrated feedback eliminates the need for external sensors, simplifying installation and reducing system complexity.
Robust Construction for Harsh Environments: With an IP64 protection rating, the SIEMENS 1FT5076-0AC01-2-Z is well-protected against dust ingress and splashing water, making it suitable for demanding manufacturing environments including metalworking shops with coolant spray and machining debris. The self-cooled design eliminates reliance on forced-air fans, reducing energy consumption and maintenance points while ensuring reliable operation in ambient temperatures up to 40°C. The IM B5 flange mount configuration with solid shaft ensures secure mechanical integration with machine tool feed axes.
