  • Technical Specifications:
    • Supply Voltage: 115 VAC 1Ø or 230 VAC 3Ø (also 400 VAC 3Ø variants exist)
    • Continuous Output: 3 A RMS
    • Peak Output: 9 A
    • DC Bus Range: 160 – 310 VDC (low voltage) or 310 – 560 VDC (high voltage)
    • Communication: SERCOS, CANopen, Profibus (depending on option)
  • Functional Features:
    • Master-Axis​ capability (can manage slave axes in multi-axis systems).
    • Integrated brake control.
    • RS-232 for setup via DriveGUI​ or WorkBench.
    • Regenerative braking support (internal chopper + external resistor).
  • Application Scenarios: Multi-axis machines, printing, converting, S300/S400 legacy systems.
  • Performance Parameters:
    • Current Loop: < 1.28 µs update.
    • Position Loop: Configurable down to 62.5 µS.
  • Material & Structural Features:
    • Book-size metal enclosure.
    • Removable terminal blocks.
    • LED status indicators.
  • Working Principle:
    • High-speed DSP executes vector control; shares DC bus in multi-axis configs; SERCOS interface synchronizes cyclic data with motion controller.
  • Installation Requirements:
    • Mount on DIN rail or panel with ≥50 mm top/bottom clearance.
    • Connect PE first; ensure bus voltage matches supply.
  • Usage Precautions:
    • SE​ firmware may not be backward-compatible with non-SERCOS controllers.
    • Disable outputs before connecting/disconnecting motor phases.
