It utilizes the latest servo motor control chips and a multi-channel data collection module, ensuring high-speed sampling, precise control, and system stability. By incorporating hardware-based design, it enhances reliability and operational consistency. -
High-Efficiency Professional Control Platform
The DSC-TT system integrates DSP (Digital Signal Processor) and MCU (Microcontroller Unit), combining DSP’s high-speed computing with MCU’s superior input/output control. This hybrid approach significantly outperforms standalone DSP or 32-bit microcontrollers. Built-in motor control modules such as PWM (Pulse Width Modulation) and QEI (Quadrature Encoder Interface) ensure stable and precise system performance. -
Parallel Sampling for Real-Time Accuracy
Featuring a specialized ASIC (Application-Specific Integrated Circuit) chip, the system enables synchronous sampling of load cells signals, eliminating the asynchronous loading and deformation errors found in older systems. This marks a breakthrough in hardware-based parallel sampling. -
Position Pulse Signal Filtering for Stability
The optical encoder module incorporates a 24-level hardware filter to refine pulse signal sampling, preventing counting errors caused by interference. This guarantees precise position accuracy, ensuring the pulse capture system operates reliably and smoothly. -
Optimized Bottom-Level Control for Faster Response
The ASIC chip offloads peripheral tasks such as sampling and condition monitoring to dedicated hardware, allowing the DSC-TT system to focus on high-speed PID (Proportional-Integral-Derivative) calculations. This enhances system responsiveness, ensuring real-time closed-loop control at the core level for unmatched precision and efficiency.
