DELTA ASD-B2-3023-F ASDA-B2 Series AC Servo Drive

Product Overview

The ASD-B2-3023-F (ASDB23023F) is a high-efficiency AC servo drive from Delta’s B2 series, engineered for cost-effective, high-reliability motion control. While the drive is rated for applications requiring robust power handling, it provides a stable output for precision positioning tasks. The B2 series is a favorite in industries such as packaging, labeling, and simple robotics, where high-speed response is needed but the advanced, high-cost features of the premium A2 or A3 series are not required. It is built to balance mechanical longevity with consistent torque delivery.

Technical Configuration

The ASD-B2-3023-F is designed for three-phase 220 V industrial power grids. It features a versatile analog control interface (0 to ±10 VDC) with a 10 kΩ input resistance, making it compatible with most standard PLC analog output modules or dedicated motion cards. The hardware includes a low-pass filter smoothing strategy to reduce high-frequency mechanical vibration, ensuring smoother movement profiles for the connected motor. Its compact physical footprint (1.72 kg) allows for high-density cabinet mounting, supported by simplified mounting requirements (14 kgf-cm screw torque).

Technical Specifications

Frequently Asked Questions

What is the difference between the B2 and A2 series?

The B2 series is positioned as a "standard" drive, focusing on essential motion control functions like speed, torque, and position control. The A2 series is a "high-performance" line that adds features like advanced E-CAM (Electronic Cam) functionality, higher-resolution encoder processing, and support for high-speed motion communication buses.

What is the purpose of the 70A fuse specification?

The 70A fuse recommendation is a critical safety parameter to protect the drive's rectifier stage in the event of a catastrophic internal short circuit or a massive grid power surge. Always follow this rating strictly to prevent hazardous failure modes during a fault.

How do I integrate this drive if I do not have a PLC with analog output?

If your PLC lacks analog capabilities, you can use a high-speed pulse output module (Pulse + Direction) to control the drive's position and speed. The ASD-B2 series supports standard pulse train commands, which are often more precise than analog voltage signals in modern digital control systems.

Installation and Operational Best Practices

• Tightening Torque: Always use a calibrated torque wrench for the mounting screws (14 kgf-cm). Under-torquing can lead to poor thermal transfer from the drive chassis to the machine frame, resulting in premature thermal derating.
• Analog Signal Noise: Because the drive uses a ±10 V analog input, the control signal is highly susceptible to interference. Use high-quality shielded twisted-pair wire. Connect the shield to the drive’s signal ground terminal only, to avoid creating a ground loop that could cause "motor jitter."
• Thermal Environment: Although the unit is compact, it generates heat during the switching process. Mount it in an enclosure with adequate ventilation. Avoid placing it directly below high-power components like VFDs or large transformers, as the ambient heat will reduce the drive's service life.
