Product Performance

Excellent control precision: Adopting IGBT sinusoidal PWM full digital control technology, the speed fluctuation rate ≤±0.1%, positioning error ≤±0.02mm (with 17-bit encoder), which can meet the high-precision motion requirements of precision processing equipment. Fast dynamic response: Torque response time ≤15ms when load changes suddenly, no overshoot, suitable for heavy-duty working conditions with frequent start-stop and forward-reverse switching.

Comprehensive protection mechanism: Fault detection response time ≤1ms, which can quickly identify abnormalities such as short circuits and overloads, cut off power output, and upload fault information through communication ports. Fault location accuracy reaches the unit level, reducing maintenance troubleshooting time. Strong system compatibility: Supports direct communication with PLCs and motion controllers; modular design facilitates function expansion and unit replacement, and can adapt to the needs of servo motors with different power levels.

Outstanding reliability: Industrial-grade components and wide-temperature design ensure a Mean Time Between Failures (MTBF) ≥1.0×10⁶ hours (MIL-HDBK-217F standard, 25℃ environment), enabling continuous and stable operation in dusty, vibrating, high/low temperature environments.
