Technical Specifications

Technical FAQs

What are the primary performance advantages of the ASDA-B3 series over previous generations?

The ASDA-B3 series increases the response bandwidth to 3.1 kHz and supports high-resolution 24-bit encoders. This results in much smoother motor operation, higher positioning accuracy, and a significant reduction in the mechanical vibration often associated with high-gain control loops.

Does this drive support internal position programming?

Yes, the "L" model supports PR mode (Position Register mode). This allows users to program up to 64 points of internal position commands, which can be triggered via digital I/O or RS-485 communication, reducing the computational load on the master PLC.

Can the ASD-B3-2023-L operate on single-phase 220V power?

The "23" designation is specifically rated for three-phase input. For a 2.0 kW load, three-phase power is mandatory to maintain DC bus stability and prevent input bridge rectification failure. Operating a 2kW drive on single-phase power will likely result in undervoltage (Uv) faults under load.

Engineering & Installation Guide

• Advanced Vibration Suppression: Utilize the B3's auto-tuning function and notch filters to eliminate mechanical resonance. The drive can automatically detect and suppress vibrations between 20 Hz and 8000 Hz, protecting mechanical components like ball screws and gearboxes from high-frequency fatigue.

• High-Density Mounting: The ASD-B3-2023-L features a more compact design than its predecessors. When mounting multiple units side-by-side, ensure a minimum gap of 10 mm between drives and provide at least 50 mm clearance at the top and bottom to allow the cooling fans to maintain an ambient temperature below 55 deg C.

• Shielding and Grounding: To satisfy 3.1 kHz high-speed communication integrity, ensure all control cables (Analog and Pulse) are shielded with the braid grounded at the drive side. Use a dedicated ground wire for the motor and drive to minimize electrical noise that could affect sensitive 24-bit encoder signals.
