Detailed content

Technical Specifications (Based on similar BDS4A-203J units):
  • Input:​ 310 VDC (approx. 4.5 A DC input side)
  • Output:​ 230 VAC equivalent (3 A/phase continuous typical)
  • Current Rating:​ Approx. 3 A continuous per phase, peak higher depending on duty
    Functional Features:
  • Digital current loop regulation with configurable gain scheduling.
  • Compatibility with resolver or encoder feedback depending on onboard interface.
  • Fault detection for over-current, over-temperature, and feedback loss.
    Structural Characteristics:
  • Compact industrial metal housing with labeled terminal blocks.
  • Separate sections for power input, motor output, and feedback/signal I/O.
  • Mounting via panel screws or DIN-rail adapter (variant-dependent).
    Application Scenarios:
  • Retrofit of legacy automation cells, winding machines, cut-to-length systems.
    Installation & Usage Notes:
  • Confirm exact feedback device jumper/software setting before applying power.
  • Ensure DC bus voltage does not exceed drive’s maximum rating (typically ~320 VDC from 230 VAC input).
  • Due to age of series, verify firmware/parameter backup before maintenance.
