The advanced servo algorithms support more features such as adaptive filtering, model tracking, vibration suppression, and friction compensation.

The dynamic braking feature in the event of a malfunction, emergency stop, or motor brake failure.

Data analysis functions support trigger and continuous modes, clearly show the servo operating status, and allow waveform scaling and playback.

Compatible with most models and motors, greatly reducing the difficulty of debugging and alignment.

Supports multiple graphical operating functions, with more user-friendly interaction, easier to get started.

Advancing control chip enhances communication and interaction capabilities, providing faster response speed and more accurate motion control.

23-bit multi-turn absolute encoder, significantly improving the device's repeatability and absolute positioning accuracy.

3.5 kHz EtherCAT high bandwidth allows the servo driver to respond to commands faster, effectively shortening the tuning time.

The servo motor meets the IP67 protection, suitable for any harsh operating environments, dustproof and moisture-proof.
