Product Description:

The XSL-230-36 is a digital servo amplifier produced by Copley Controls within the XENUS Digital Loop Modules series. The module serves as a three-phase IGBT inverter that regulates current delivered to brushless motors, allowing coordinated motion in packaging lines, robotics, and other factory equipment. By housing the control loops on a compact board, the module allows the power stage to be mounted close to the axis, reduces electromagnetic emissions along cable runs, and supports distributed control networks that rely on deterministic current regulation.

The drive supplies a continuous output of 12 A DC, providing motors with steady torque under rated thermal conditions. A current-loop update rate of 15 kHz enables rapid correction of phase currents, while the carrier switches at 30 kHz so acoustic noise stays above the audible range. Stable operation requires at least 400 μH of line-to-line inductance, matching most medium-inertia servomotors. Analog velocity or torque commands are digitized with 12-bit precision, and the module accepts 12 optically isolated inputs plus three sourcing outputs for limit switches, home sensors, or fault relays. Logic circuitry draws no more than 500 mA from the 24 V control bus, and the built-in inverter topology supports direct connection to star or delta motor windings.

During transients, the amplifier can deliver a peak current of 36 A DC for one second, giving machines the additional thrust needed for acceleration or shock loads. For step-and-direction applications, the position interface processes pulses at up to 2 MHz, and an incremental encoder channel reads quadrature signals at a 5 MHz line frequency to preserve accuracy at high spindle speeds. Excess kinetic energy is returned to the DC bus, and the regeneration circuit can dissipate 4 kW when paired with a braking resistor of at least 15 Ω. The module measures 7.55 × 5.57 × 2.57 inches, allowing it to fit into shallow enclosures while leaving room for airflow and cabling.
