CDHD2 is the second generation of the CDHD servo drive family. It features ease of use and advanced control algorithms. The comprehensive feature set of the CDHD2 allows to build more accurate and more efficient machines.

CDHD2 current loop design achieves an industry leading frequency response of 3-5 kHz. Advanced autotuning reduces tracking error and settling time to almost zero, and an innovative anti-vibration algorithm eliminates mechanical resonance. CDHD2 supports virtually any motor, any feedback type, and any I/O requirement. It offers seamless commissioning through ServoStudio software or direct terminal access, with all–in-one tuning of current, velocity, and position control loops.
