Key Functions
- Simplified Implementation: Inherits B3-series features but with simplified wiring and a more intuitive interface.
- Control Modes: Supports PT Mode (Pulse Input), Speed, and Torque control.
- Vibration Suppression: Built-in algorithms automatically handle mechanical resonance to protect your machinery.
- Communication: Includes RS-485 for standard industrial communication.
The primary function of the ASD-E3-0421-L is to act as a high-speed intelligence hub for a 400W servo motor. It processes control signals (like pulses or analog voltages) and translates them into precise electrical current to drive the motor with extreme accuracy
Key Functional Modes
As a member of the
ASDA-E3 series, this drive supports three standard control modes: [

- Position Mode (PT Mode): Controls the exact location and angle of the motor shaft using pulse-train commands. This is the "L" type's specialty.
- Speed (Velocity) Mode: Regulates the rotation speed (RPM) precisely, often using analog voltage signals or internal register settings.
- Torque Mode: Controls the amount of force the motor applies, which is essential for applications like tension control in winding machines. [1, 2, 3, 4]
Advanced System Functions
- 24-bit Feedback Processing: It decodes over 16 million pulses per revolution from the motor's encoder, enabling incredibly smooth motion even at very low speeds.
- Auto-Tuning: Features a user-friendly auto-tuning algorithm that automatically calculates the optimal "gain" settings for your machine's specific load, reducing setup time.
- Vibration Suppression: Automatically detects and cancels out mechanical resonance, preventing the machine from shaking or humming during operation.
- Diagnostic Protection: Continuously monitors for faults such as over-current, over-voltage, and encoder errors to prevent hardware damage. [1, 2, 3, 4, 5, 6]
Comparison: E3 vs. B3
While it inherits the core performance of the
ASDA-B3 series, the
E3 series is functionally designed for
faster implementation with simplified wiring and a more intuitive interface for standard transport and transmitting tasks. [
