XEC-230-12

XEC-230-12 is a Copley Controls module in the XENUS Digital Loop Modules series. Its analog input accepts ±10 Vdc and has an input resistance of 5.05 kΩ, establishing the voltage range and impedance for analog command signals. The module delivers 6 Adc of continuous current and 12 Adc of peak current for up to 1 second. A minimum load inductance of 200 µH is required, while the maximum single-phase mains current is 9.4 Arms. The 940 µF bus capacitance supports energy storage and DC-bus stabilization.

The current loop operates at 16 kHz for rapid current regulation, while velocity and position loops run at 4 kHz for motion control updates. Digital position processing supports a 4 MHz rate, and the quadrature A/B input handles up to 2 million lines per second for encoder feedback. Phase-current measurement uses 12-bit resolution, providing 4,096 quantization levels. The PWM output has a minimum pulse width of 220 ns, setting the shortest switching command it can produce.

The regenerative circuit handles 20 W of continuous power to dissipate returned motor energy. Regeneration begins at 390 Vdc with a tolerance of ±2 Vdc, controlling excess DC-bus voltage during deceleration.
