The ASD-A2-0121-E is part of Delta’s ASDA-A2-E high‑performance AC servo drive family, which adds an EtherCAT interface and extended I/O to the proven ASDA‑A2 platform. This model provides 0.1 kW (100 W) rated output power at 220 V AC, supports single‑phase or three‑phase 220 V input, and delivers 0.9 Arms continuous output current with up to 2.7 Arms maximum instantaneous current, making it suitable for small‑power, high‑precision axes in packaging, electronics, and light machinery.
The A2‑E series complies with EtherCAT (IEC 61158, IEC 61800‑7, CiA402 CoE) and passes ETG conformance testing, enabling high‑speed, synchronized multi‑axis control via standard EtherCAT masters. It supports all CoE device profile modes (position, velocity, torque), electronic gearing and camming, making it ideal for flying shear, rotary cutoff, and synchronized motion applications. The drive also offers an extension digital input port (CN7) so users can connect external encoders and implement full closed‑loop control with improved positioning accuracy.
Paired with Delta ECMA series servo motors, the system can use 20‑bit incremental encoders (1,280,000 pulses/rev), providing extremely fine resolution and stable low‑speed rotation. Built‑in vibration suppression filters help minimize low‑frequency resonance at machine edges, improving performance on flexible machines such as cranes or long‑arm mechanisms. The ASDA‑A2‑E series includes advanced auto‑tuning, notch filters, electronic cam (E‑CAM) and comprehensive alarms, making commissioning and optimization easier.
Typical applications for ASD-A2-0121-E include small indexing axes, labelers, pick‑and‑place units, electronic assembly machines, and any EtherCAT‑based multi‑axis system requiring a 100 W servo drive with high precision and synchronization.
