The Advantage of Absolute Value Servo Motor Stage Machinery

Absolute Value Servo Motor Stage Machinery is a high-end stage drive system based on multi-turn absolute value encoder technology, specifically designed for mechanical devices that require high-precision positioning, power-off position memory, and rapid response in theaters, concerts, and live performances. By deeply integrating absolute value servo motors with stage machinery (such as lifting stages, rotating mechanisms, sliding trolleys, servo hoists and winch machine), it achieves millimeter-level positioning accuracy and motion without cumulative error under full closed-loop control. This completely eliminates the difficulty of traditional incremental encoders needing to return to zero repeatedly, ensuring absolute reliability and continuity in the performance process, making it suitable for high-demand, high-risk artistic presentation scenarios.

The stage machinery developed by YZ DITEC (including servo hoists, sliding trolley, winch machine, rotating stage and lifting stages) is centered around absolute value servo motors, pursuing greater safety, precision, and speed.

Core Functions and Advantages

1. Absolute Position Memory, No Need to Return to Zero

• Utilizes multi-turn absolute value encoders, permanently recording mechanical motor position information even after power loss. After restarting, there is no need for origin reset operations, avoiding delays caused by interruptions during performances or emergency power outages.
• Supports breakpoint continuation of position data, allowing for instant recovery to the state before the interruption after an unexpected shutdown, ensuring "zero tolerance" in the performance process.

2. Millimeter-Level Precision and Dynamic Response

• 23-bit high-resolution absolute value encoders (with a resolution of ±0.1mm), combined with adaptive disturbance resistance algorithms, achieve ultra-low tracking errors (±0.1mm) during high-speed motion (maximum speed of 5000 rpm).
• Full closed-loop control architecture compensates in real-time for backlash and deformation in the mechanical transmission chain (gearboxes, lead screws), eliminating precision degradation caused by long-term use.

3. Multi-Motors Coordination and Intelligent Safety

• Supports EtherCAT high-speed bus networking, allowing a single main controller to synchronize and drive up to 128 motors with a synchronization accuracy of ≤1μs, meeting the stringent timing requirements for multi-motors linkage in stage machinery (such as rotating and lifting composite actions).
• Features like over-limit emergency stop and overload prediction ensure the safety of performers and equipment.

Application Scenarios

• High-Precision Stage Positioning: Millimeter-level synchronization for theater lifting platforms and precise start-stop for rotating stages in concerts.
• Outdoor Complex Environments: Interference-resistant operation of water curtain machinery and wind and rain effect equipment in live performances.
• Rapid Scene Change Requirements: Instant reset and seamless switching for multi-act theatrical scenes.

Customer Value

• Zero Risk in Performances: Absolute value encoders eliminate position loss, preventing performance accidents caused by reset failures.
• Efficiency Improvement: Eliminates daily device zeroing time, shortening setup and rehearsal cycles.
• Long-Term Cost Optimization: Maintenance-free design reduces operational costs, and a lifespan of over 10 years decreases equipment replacement frequency.
