Product Overview

The ASD-B2-1521-F (ASD-B2-1521-F) is a high-performance AC servo drive from Delta’s ASDA-B2 series, engineered for precision motion control applications. Rated for 1500W of output power, this drive is designed to deliver rapid, accurate positioning and speed control in automated machinery. Its robust architecture and advanced control loops make it an ideal choice for high-speed indexing, multi-axis robotic arms, and high-precision CNC positioning systems. By facilitating superior dynamic response, the ASD-B2-1521-F ensures high throughput and exceptional repeatability in demanding industrial production environments.

Technical Configuration

This drive is optimized for single-phase 220V power input, simplifying integration into facilities where standard utility connections are available. It features an advanced control interface with a 0 to ±10 VDC voltage range, providing versatile compatibility with external PLC or CNC controllers. To ensure signal integrity, the input circuitry incorporates a 10 kOhm input resistance with a 2.2 µs time constant, complemented by a low-pass smoothing filter strategy that effectively mitigates high-frequency noise interference, ensuring that positioning commands remain accurate and stable even in electrically noisy industrial zones.

Technical Specifications

FAQs

What is the function of the low-pass filter in the control input?

The low-pass filter is designed to remove high-frequency electrical noise from the ±10 VDC control signal. By smoothing the input command, it prevents the drive from reacting to extraneous interference, thereby maintaining high precision and stability in motor positioning.

What are the recommended safety protection devices for this drive?

For reliable installation, use a 20 A circuit breaker and a 40 A fuse as specified for this power rating. These components protect the drive’s internal rectifiers and power stage from overcurrent conditions, line surges, and short-circuit faults.

Is this servo drive compatible with Delta motors?

The ASDA-B2 series is purpose-built to work in conjunction with Delta’s ECMA series servo motors. To ensure full performance and functionality, always match the drive with the corresponding motor model designated for this power class.

What is the required mounting torque for the M4 screws?

For secure mechanical installation that withstands operational vibrations, tighten the M4 x 0.7 mounting screws to a torque of 14 kgf-cm.

Field Commissioning & Safety Guidelines

• Proper Grounding: The drive must be connected to a low-impedance earth ground to prevent electrical noise from causing positioning errors. Ensure all motor power cables are shielded, and terminate the shield directly to the drive’s ground terminal.

• Signal Isolation: To preserve the accuracy of the ±10 VDC control command, route all low-voltage signal cabling through dedicated conduits separate from high-power motor cabling and AC power lines to avoid inductive coupling.

• Thermal Environment: While the unit features internal cooling, ensure it is installed in a clean, dry control panel. Maintain a minimum clearance of 50 mm above and below the drive to ensure adequate heat dissipation from the heatsink.
