About ASD-E3-2023-L Delta B2 Series Driver - 2000W
The ASD-E3-2023-L is a 2000W (2kW) high-performance servo drive from Deltas advanced
ASDA-E3 series. While you mentioned the B2 series, the E3 is its modern, high-bandwidth successor, offering a
25% size reduction and significantly faster response times. [

Core Function
The drive acts as the power and logic controller for your ECM-E3M-E21320SSE motor:
- Precision Actuation: Translates PLC commands into high-power electrical output with a 2.5 kHz response bandwidth, providing smooth, sub-micron positioning.
- Control Modes (-L Model): Supports Pulse Train (PT) for traditional position control, Analog Voltage for speed/torque, and RS-485 Modbus for digital monitoring.
- Vibration Suppression: Automatically detects and filters out mechanical "shaking" at frequencies up to 5,000 Hz, which is critical for moving large 2kW mechanical loads.
- Smart Tuning: Features advanced Auto-Tuning that automatically calculates the machine's mechanical inertia to optimize performance. [1, 2, 4]

The Delta ASD-E3-2023-L is the high-power control hub for a 2.0kW servo system. Its primary function is to convert low-voltage signals from your controller (like a PLC) into the high-current electrical pulses required to move a 2000W motor with absolute precision.
As an E3 Series "Basic" Type (-L) driver, its specific functions include:
1. High-Bandwidth Motion Control
- Closed-Loop Processing: It continuously analyzes the 24-bit feedback from the motors encoder. If the motor is even a fraction of a degree off its path due to load resistance, the drive corrects it 2,500 times per second (2.5 kHz bandwidth).
- Pulse Train (PT) Mode: Functions as a high-speed follower, moving the motor a specific distance and speed based on pulses received from a PLC.
- Analog Control: Uses a -10V to +10V signal to function as a variable speed or torque regulator, common in tension-control systems.
2. Mechanical Optimization
- Smart Auto-Tuning: The drive functions as its own technician. It can perform a test move to calculate the mechanical weight (inertia) of your machine and automatically set the "Gains" for the smoothest possible motion.
- Advanced Vibration Suppression: Large 2kW systems often "shake" or hum. This drive scans for mechanical resonances (up to 5000Hz) and applies notch filters to cancel out the shaking, much like noise-canceling headphones.
3. System Protection & Monitoring
- Electronic Gear Ratio: It can mathematically scale the incoming pulses so that your PLC can command simple units (like 10.0mm) without complex external math.
- Holding Brake Management: It manages the timing for your motor's SSE (Brake) mechanism, ensuring the brake is released before the motor tries to move and engaged after it stops.
- Safe Torque Off (STO): A dedicated hardware safety function that immediately cuts power to the motor's transistors during an emergency without needing to cut the main power to the drive.
Functional Comparison: E3 vs. B2 Series
While you noted it as "B2 Series," this E3 driver is a significant functional upgrade:
- Accuracy: Supports 24-bit encoders (16.7M pulses/rev) vs. B2's 17-bit (160k pulses/rev).
- Response: Reacts 2.5x faster, which is critical for the heavy momentum of a 2kW load.
- Size: It is roughly 25% slimmer, allowing more drives to fit in the same control panel.
