Detailed content

  • Technical Specifications:
    • Input Supply: 3 × 230 VAC (±10 %), 50/60 Hz
    • DC Bus: approx. 325 VDC
    • Continuous Output Current: 12 A
    • Peak Output Current: higher than continuous for short duration per BDS3 stack
    • Feedback Support: resolver or incremental encoder
    • Control Command: analog ±10 V speed or torque reference
    • Enclosure: IP20 chassis module
    • Cooling: natural convection or rack-assisted airflow
  • Functional Features:​ Current-limited PWM power stage; adjustable PI speed loop; fault LED indicators; overcurrent, overvoltage, undervoltage and short-circuit protection; mounts in BDS rack or standalone panel with separate DC bus supply.
  • Material / Structure:​ Sheet-steel housing; printed circuit board with discrete transistor/IGBT bridge; rear-edge connector for bus and control signals; front trim with potentiometers and status LEDs.
  • Working Principle:​ Rectifies 3-phase AC to fixed DC bus, synthesizes 3-phase sinusoidal current via PWM, regulates q-axis current from feedback device, closes outer speed loop via analog command.
  • Application Scenarios:​ Retrofit of 1990s–2000s machine tools, textile machines, winding/unwinding stations, single-axis packaging machinery using Seidel 6SM or early AKM motors.
  • Installation Requirements:​ Vertical mount in grounded steel cabinet; separate shields for power and feedback; 24 VDC control supply if required by rack; maintain specified air clearance above/below module.
  • Usage Notes:​ Obsolete product, no longer in Kollmorgen active catalog; suffix 01-400 denotes firmware/option configuration; never swap without verifying motor winding voltage and feedback type; do not run without DC bus precharge and earth protection.
