Technical Specifications:
  • Series: SERVOSTAR 20330
  • Rated Output Current: 30 A continuous
  • Input Bus: 320 VDC typical (rectified 230 VAC)
  • Control Modes: Torque, velocity, position
  • Feedback Support: Incremental encoder, resolver, sine-cosine encoder
  • Communication: CANopen (CNS variant)
  • I/O: 8 digital inputs, 4 digital outputs, 2 analog inputs
  • Dimensions: 60 × 170 × 210 mm (approx.)
  • Protection: IP20
  • Compliance: CE
    Functional Features:​ Autotuning, electronic gearing, registration/capture inputs, firmware-selectable motor parameters, CANopen DSP-402 profile.
    Construction / Materials:​ Sheet-steel chassis, PCB with DSP controller, IGBT power stage, built-in fan-less convection cooling.
    Working Principle:​ DC-bus IGBT inverter controlled by DSP; current loop closed at >10 kHz, velocity/position loops closed via encoder/resolver interface.
    Mounting Requirements:​ Panel mount vertical orientation, 50 mm clearance top/bottom for convection, grounded metal panel, separate 24 VDC control supply.
    Usage Notes:​ CNS firmware requires CANopen master. Bus voltage must be regulated; regen resistor mandatory for frequent decel. Never hot-swap motor leads under power.
