  • Technical Specifications & Performance Parameters:
    • Supply Voltage: 3-phase 60–172 VAC (±10%), 50/60 Hz
    • Rated DC Link Voltage: 240 V
    • Continuous Ballast Power: ~135 W
    • Pulse Ballast Power: 5.4 kW
    • Minimum Motor Inductance: 5.0 mH
    • Peak Standstill Current: Specified per sub-model (typical continuous ~rated, peak several times higher for short duration)
    • Operating Temp: 0–40°C
    • Humidity: 5–85% non-condensing
    • Altitude: ≤1000 m (derating above)
    • Protection: IP00 (touch protection at terminals)
    • Weight: ~1.4 kg
    • Cooling: Natural convection (forced air recommended in tight enclosures)
  • Function Features:
    • Built-in -w- characteristic ballast circuit​ for energy-balanced regenerative dissipation.
    • Differential analog setpoint inputs, enable input, limit-switch inputs.
    • PI current and speed controller with trimmer potentiometers.
    • Color LED diagnostics for ready/fault.
    • Optional external 24VDC aux supply.
  • Applications: Semiconductor manufacturing equipment, test stands, packaging machines, retrofits of older SM-motor systems.
  • Material & Structure: Eurocard-format PCB (approx. 199×100 mm) with SMD components, 3-phase power section with V-MOS transistors, smoothing capacitors, finned metal chassis for convection.
  • Working Principle: Analog 4-quadrant PWM transistor output stage; receives ±10V speed/torque setpoint; commutates motor using rotor position from RLG/tacho; ballast circuit manages decel energy; PI controllers stabilize current/speed loops.
  • Installation Requirements: Mount vertically in enclosed steel cabinet with unobstructed airflow; ensure minimum clearances for convection; ground analog signal shields separately from power ground.
  • Precautions: This is an analog​ unit—sensitive to electrical noise; verify tacho polarity before enabling; ensure ballast circuit is intact; no touch protection (IP00)—install in secure enclosure; observe max altitude/humidity limits.
