The ASD-E3-0421-L is a 750W high-performance servo drive from the ASDA-E3 series. It is the upgraded, modern successor to the older B2 series, offering significantly better speed and precision in a smaller package.
Key Functions
- High-Speed Control: It functions as the "brain" for your ECM-E3M-C20807SSE motor, processing commands up to 2.5 times faster than the older B2 series.
- Vibration Suppression: It automatically detects mechanical shaking (resonance) in your machine and uses notch filters to cancel it out, ensuring smooth motion.
- Command Modes (-L Model):
- Pulse/Direction: For traditional PLC positioning.
- Analog Input: For variable speed or torque control.
- RS-485: For digital parameter setup and monitoring via Modbus.

Why use E3 instead of B2?
While you noted it as a B2 series, the E3 series offers:
- Higher Resolution: Better positioning accuracy for your 750W motor.
- Smaller Size: Takes up less rail space in your panel.
- Auto-Tuning: Much easier to set up; the drive tunes itself to your machine's weight automatically.
