Product Overview

The ASD-A2-2043-M (ASDA22043M) is a high-performance 2.0 kW AC servo drive from Delta’s advanced ASDA-A2 series, specifically designed for 400V three-phase power environments. This drive is a critical component for high-torque industrial applications, such as large-scale CNC machining centers, heavy-duty printing presses, and synchronized gantry systems. The ASDA-A2 series is engineered for high-precision motion control, featuring a 1 kHz response bandwidth and support for 20-bit high-resolution encoders. The "M" type model is a specialized configuration within the A2 family, offering integrated CANopen communication capabilities, which enables seamless integration into high-speed distributed control networks and reduces the complexity of field wiring in multi-axis automation architectures.

Suffix Breakdown

• ASD: AC Servo Drive (Product Type).

• A2: A2 Series (Advanced functional series with E-Cam and CANopen support).

• 20: 2.0 kW Rated Output Power.

• 43: 400V Input Voltage, 3-Phase.

• M: Model Type (Integrated CANopen communication interface).

Technical Specifications

Technical FAQs

What is the advantage of the "M" type CANopen interface for multi-axis systems?

The CANopen interface allows the ASD-A2-2043-M to be daisy-chained with other drives, allowing a single master controller to manage complex motion profiles via a high-speed digital bus. This drastically reduces the I/O count on the PLC and provides real-time diagnostic feedback and parameter modification over the network.

Can this drive handle 220V power if 400V is unavailable?

No. The "43" designation indicates the hardware is specifically wound and rated for a 400V class supply. Attempting to run this drive on 220V will result in an undervoltage fault, while exceeding the 480V upper limit will lead to immediate and permanent failure of the DC bus capacitors and power modules.

Does this model support internal electronic cam (E-Cam) functions?

Yes. Like all A2 series drives, the ASD-A2-2043-M features a built-in E-Cam function with up to 720 points for smooth contouring and flying-shear applications. This allows the drive to handle complex motion relationships locally, offloading the calculation burden from the master motion controller.

Engineering & Installation Guide

• 400V Power Safety & Filtering: Given the high voltage class, always install a dedicated 3-phase AC reactor on the input side to suppress harmonic distortion and protect the drive from power surges. Ensure the 400V power cables are shielded and kept at least 300 mm away from low-voltage signal wires (CANopen and encoder lines) to prevent EMI-induced position errors.

• CANopen Network Termination: In a CANopen network, a 120-ohm termination resistor must be placed at both physical ends of the trunk line. Use high-quality twisted-pair cabling specifically rated for CANbus (typically 120-ohm impedance) to ensure data integrity at high baud rates.

• Thermal Dissipation: The 2.0 kW power module generates significant heat during heavy duty cycles. The drive must be mounted vertically with at least 100 mm of clearance above and below the unit. In enclosed cabinets, ensure an active cooling fan is positioned to move air across the drive's heat sink to maintain an internal temperature below 55 deg C.
