The ASD-E3-1021-L is a 1000W (1kW) high-performance servo drive from Deltas advanced ASDA-E3 series. While you mentioned the B2 series, this is actually the modern, high-speed successor designed to drive 1kW motors like your ECM-E3M-E21310SSE.
Function
The drive acts as the "brain" and "power station" for your 1kW motor:
- Precision Driving: It converts command signals from your PLC into high-power electrical current to move the 1kW motor with a 2.5 kHz response bandwidth (2.5x faster than the older B2 series).
- Closed-Loop Feedback: It continuously reads the 24-bit encoder data from the motor to ensure the machine never "loses steps," even under heavy loads.
- Vibration Suppression: It automatically scans and filters out mechanical resonances up to 5000 Hz, which is essential for large machines that tend to "shake" at high speeds.
- Command Modes (-L Model): Supports Pulse/Direction (positioning), Analog Input (speed/torque), and RS-485 Modbus (control/monitoring).
Physical Dimensions & Weight (Inches)
The E3 series is designed to be "book-style" (slim) to save space in your electrical panel.

Key Difference from B2 Series
If you are replacing a B2 series driver, the E3 is about 20% smaller, offers much better auto-tuning (it learns your machine's weight automatically), and handles the high-resolution 24-bit encoder which the B2 cannot.
