ASD-A2-1521-M Servomoteur haute performance DELTA ASDA-A2 série 1,5 kW

Product Overview

The ASD-A2-1521-M (ASDA21521M) is a flagship AC Servo Drive from Delta’s high-performance ASDA-A2 series, engineered to meet the demanding requirements of modern motion control. Providing a rated output of 1.5 kW, this drive is designed for 220 V single-phase or three-phase input environments. The "M" type model is a specialized version that features a built-in CANopen communication interface, enabling high-speed distributed control and seamless integration into motion control networks. With advanced features such as electronic cam (E-CAM) functionality, vibration suppression, and high-resolution encoder support, the ASD-A2-1521-M is the ideal choice for precision labeling, flying shears, rotary cut-offs, and complex multi-axis synchronization tasks.

Technical Configuration

The ASD-A2-1521-M is built on a sophisticated digital signal processing (DSP) architecture that supports a wide array of control modes including Position, Speed, and Torque control. The drive features dual-mode communication, incorporating both RS-232/RS-485 via Modbus and the high-speed CANopen protocol (DS402). A standout feature of the A2 series is the integrated E-CAM function, which allows for 720 points of custom cam profiles, managed internally to reduce the computational load on the master PLC. The drive also supports full-closed loop control via an external second encoder interface to compensate for mechanical backlash and ensure the highest possible end-of-arm accuracy.

Technical Specifications

Technical FAQs

What is the specific advantage of the "M" type model in the A2 series?

The "M" type designation indicates the inclusion of the CANopen communication port. This allows the drive to operate as a standard DS402 slave node, facilitating high-speed bus communication with motion controllers. It is particularly effective for systems requiring coordinated motion between multiple drives where traditional pulse-train wiring would be too complex.

How does the Built-in E-CAM benefit a 1.5 kW application?

In applications like high-speed packaging or rotary cutting, the drive can internally calculate the master/slave relationship using the E-CAM table. This eliminates the delay of transmitting position commands over the network for every cycle, resulting in much smoother motion and higher production throughput compared to drives relying solely on external PLC command calculation.

Can I run this drive on standard single-phase residential power?

Yes, the "21" in the part number indicates it is compatible with 220 V single-phase input. However, at the 1.5 kW power level, ensure your circuit breaker and wiring are rated for the high input current (typically around 16-20 A for single-phase operation) to prevent nuisance tripping during rapid motor acceleration.

Engineering & Installation Guide

• CANopen Termination: When using the ASD-A2-1521-M in a network, ensure that a 120 Ohm termination resistor is placed at the physical beginning and end of the CAN bus line. Failure to terminate the bus correctly will lead to signal reflections and intermittent communication errors (Node Guarding or Heartbeat failures).

• Vibration Suppression Tuning: The A2 series features advanced automatic high-frequency notch filters and low-frequency vibration suppression. During commissioning, use the ASDA-Soft software to run the "Auto-Tuning" function. This will automatically identify the resonance frequency of your mechanical linkage and configure filters to eliminate "ringing" and noise during high-speed stops.

• Regenerative Resistor Sizing: For 1.5 kW loads involving high inertia or vertical movement, the built-in regenerative resistor may not be sufficient. Monitor the "d1.05" (Regenerative load ratio) parameter. If it consistently exceeds 80 percent, an external braking resistor must be connected to the P and D terminals to prevent Overvoltage (AL001) faults.
