    • Rated DC-Link Voltage: 240 V
    • Rated Output Current: 3 A (continuous 4Q operation)
    • Peak Output Current: 7.5 A (max ~5s)
    • Ballast Circuit Pulse Power: 5.4 kW
    • Ballast Continuous Power: 135 W
    • Minimum Motor Inductance: 5.0 mH
    • Weight: Approx. 1.4 kg
    • Protection: IP 00 (touch protection on power terminals)
    • Ambient Temp: 0–40 °C (derating 2.5%/°C up to 55 °C)
    • Aux Voltage: +/-15 V, 24 V DC (optional)
  • Functional Features:
    • 4-quadrant V-MOS transistor output stage.
    • Integrated ballast circuit with w-characteristic for energy dissipation.
    • PI current and speed controller with trimmer adjustment.
    • Differential setpoint inputs, enable input, limit-switch inputs.
    • Monitoring for actual current, overvoltage, output stage temperature, short-circuit protection.
    • LED indicators for operational readiness/fault.
  • Application Scenarios: Retrofit of older SM-series motor systems, test rigs, semiconductor handlers, packaging machines using analog drives.
  • Structural & Material Characteristics: Double Eurocard format (220 x 233.4 x 45 mm), DIN 41612 C64/D32 backplane connectors, SubD 9-pin, Combicon screw terminals, natural convection cooling fins.
  • Working Principle: Analog PI regulators compare setpoint voltage with tacho/feedback signals to drive PWM generator controlling MOSFET bridge; DC-link energy managed by ballast resistor during deceleration.
  • Installation Requirements: Closed switchgear cabinet, vertical mount; natural convection requires uninterrupted airflow; max altitude 1000m; 24V aux supply if option fitted.
  • Usage Precautions: Obsolete/discontinued product; no modern bus communication; ensure minimum motor inductance 5.0 mH to prevent oscillation; ballast dissipation must be managed in cabinet thermal design; IP 00 requires touch-safe enclosure.
