Product Performance

High speed control precision: Adopting PI adaptive adjustment algorithm, speed fluctuation rate ≤±0.1%, enabling smooth speed regulation from 0.1rpm to rated speed, suitable for precision transmission scenarios. Accurate position positioning: Supports pulse/bus command control, positioning error ≤±0.01mm (with 17-bit encoder), meeting high-precision requirements of machine tools and robots.

Fast dynamic response: Torque response time ≤10ms when load changes suddenly, no overshoot, adaptable to working conditions with frequent start-stop and forward-reverse switching. Comprehensive protection mechanism: Fault detection response time ≤1ms, which can quickly cut off power output and lock fault status to avoid damage to motors and controllers.

Strong system compatibility: Supports direct communication with PLC and motion controllers, compatible with Reliance automation systems and third-party equipment; modular design facilitates function expansion and maintenance. Excellent reliability: Industrial-grade components and wide-temperature design ensure Mean Time Between Failures (MTBF) ≥1.0×10⁶ hours, adapting to harsh industrial environments with dust and vibration.
