Dimensions: 220 × 233.4 × 45 mm double Eurocard, weight 1.4 kgFunctional Features: 4-quadrant regeneration, built-in ballast circuit, analog velocity/torque command, plug-in option cards for limit switches/ramp.Structure & Materials: Double-Eurocard PCB, heatsinked IGBT module, DIN 41612 C64/D32 backplane connectors, D-sub resolver/tacho port.Working Principle: Analog setpoint compared to tacho/encoder-derived feedback, PI current controller drives 4-Q IGBT bridge, regenerated energy dumped to ballast resistor when DC bus exceeds threshold.Installation Requirements: Mount vertically in 19” subrack with backplane, forced air above 12 A or >40 °C, 4 mm² power terminals, 24 V aux if option fitted.Precautions: IP00 means no touch protection—subrack must be enclosed; never operate without ballast load resistor connected; motor inductance must exceed 2.5 mH.
