About ASD-A3-7543-E Delta Servo Driver 7500W
The Delta ASD-A3-7543-E is a heavy-duty
7500W (7.5 kW) AC servo drive from the
ASDA-A3 series. The
"-E" suffix signifies that this model is equipped with a high-speed
EtherCAT communication interface, making it ideal for highly synchronized multi-axis industrial applications operating on
400V 3-phase power.
Dimensions and Weight
As one of the higher-power units in the series, it uses a large
Frame G chassis to manage heat and power delivery:
- 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). [1]
Key Performance Specifications
- Rated Power Output: 7500 W (7.5 kW).
- Input Voltage: 3-phase 380V ~ 480V AC.
- Communication: EtherCAT, which supports ultra-fast synchronization with cycle times as low as 125s.
- Responsiveness: 3.1 kHz bandwidth, providing rapid acceleration and minimal settling time for heavy-duty machinery.
- Encoder Precision: Supports 24-bit absolute encoders, delivering 16.7 million pulses per revolution for exceptional positioning accuracy. [1, 2, 3, 4, 5]
Advanced Industrial Features
- Vibration Suppression: Features automatic notch filters (up to 5 kHz) that identify and eliminate mechanical resonance, which is critical for stabilizing large mechanical structures under high-torque loads.
- Energy Efficiency: Includes a multi-axis DC-bus sharing design, allowing the drive to recycle energy generated during motor braking to power other drives on the same bus.
- Safety (STO): Integrated Safe Torque Off function to immediately cut motor power during emergencies while keeping the EtherCAT communication active for status reporting.
- Motion Functions: Built-in Electronic Cam (E-CAM) and PR mode with 99 user-defined paths for complex movements. [1, 2, 3, 4, 5]
