III. Detailed Explanation of Product Functions

3.1 High-performance Servo Control

Based on MDS dedicated servo algorithm, deeply optimized for permanent magnet synchronous motors, providing extremely high dynamic response speed and positioning accuracy. Resolver feedback ensures stable acquisition of rotor position signals in high-speed, high-temperature, and strong vibration environments, achieving precise closed-loop control.

3.2 Flexible Multi-mode Control

Supports three core control modes: speed, torque, and position. Can be seamlessly switched through external I/O or bus instructions. Whether it is continuous operation requiring precise speed, instantaneous load requiring large torque output, or micron-level positioning point control, it can perfectly adapt. 3.3 Stable and reliable operation guarantee

Built-in 150% rated current short-term overload capacity, easily handling impact loads. The complete electrical protection mechanism comprehensively monitors key parameters such as voltage, current, and temperature, responding rapidly in case of abnormalities and effectively protecting the driver and motor from damage.

3.4 Modular architecture and convenient expansion

The modular design of base + control unit is adopted. This model (MDX60A) is a pure power base and requires the selection of MDX61B control unit to achieve intelligent control and bus communication. This architecture allows users to flexibly configure according to project requirements, reducing costs and facilitating later maintenance and upgrades.

3.5 Intelligent debugging and monitoring

Combined with SEW MOVITOOLS software, it can perform rapid parameter setting, operation status monitoring, oscilloscope waveform analysis, and fault diagnosis. It has a rich set of parameters, supports self-tuning of motor parameters, and can quickly match different characteristics of servo motors to optimize control performance.
