About ASD-A3-7543-M Delta Servo Driver 7500W
The Delta ASD-A3-7543-M is the heavy-duty 7500W (7.5 kW) flagship model in the ASDA-A3 series. It is designed for high-torque industrial applications like CNC machining centers, large-scale printing, and heavy-load robotics.
Dimensions and Weight
As the most powerful unit in this series, it requires the largest frame size for thermal management:
- Width: ~7.87 inches (200 mm)
- Height: ~15.75 inches (400 mm)
- Depth (Length): ~9.06 inches (230 mm)
- Weight: Approximately 22.0 lbs (10.0 kg).
Key Specifications
- Rated Power Output: 7500 W (7.5 kW)
- Input Power: 3-phase 380V ~ 480V AC.
- Communication: Built-in CANopen (indicated by "-M"), plus RS-485 and USB configuration ports.
- Control Performance: Maintains the series-standard 3.1 kHz bandwidth, which is industry-leading for a drive at this power level.
- Encoder Compatibility: Specifically paired with Delta's high-inertia motors featuring 24-bit absolute encoders.
Key Performance Functions
- Electronic Cam (E-CAM): Built-in functionality for complex synchronized motion without needing an external motion controller.
- High-End Vibration Control: Uses advanced notch filters to stabilize large mechanical structures, preventing the "ringing" or oscillation common in 7.5 kW high-inertia systems.
- Energy Efficiency: Includes a built-in DC Bus sharing capability, allowing multiple drives to share regenerative energy and reduce power consumption.
- Safety Standard: Equipped with Safe Torque Off (STO), ensuring the drive meets international SIL2/PLd safety requirements.
