Product Description:
The XEL-230-18-R is a digital loop module manufactured by Copley Controls for the XENUS Digital Loop Modules series. It is installed inside automated equipment to close current, velocity, and position loops for brushless or stepper motors, translating command inputs into high-frequency pulse-width-modulated output. This makes the unit a servo drive element in conveyor systems, pick-and-place stations, and other motion axes that require deterministic regulation. Because loop closure occurs in the module, response to changing load conditions can remain quick without relying on a distant control stage. The compact form factor lets it mount close to the actuator, which helps reduce cable losses and simplify panel layout.
The analog interface samples at a resolution of 16-bit, allowing fine scaling of torque or speed commands before they enter the high-speed current loop that runs at 16 kHz. During steady operation, the module can deliver 6 Adc of continuous phase current, while transients up to 18 Adc are available for 1 s to overcome inertia or friction. Control electronics draw no more than 500 mA from the low-power supply, and pulse generation uses a 220 ns minimum PWM pulse width to maintain switching fidelity. These limits keep output predictable when the drive is paired with motors that match the 4 kHz velocity and position update rate. That control structure supports smooth low-speed operation and stable torque delivery during frequent starts and stops.
When connected to the AC line, the drive draws up to 10.1 Arms from a single-phase supply or 6.4 Arms from a three-phase supply, which allows different cabinet power arrangements. The motor side must present at least 200 µH of inductance so switching ripple stays within safe limits. For absolute rotor feedback, the resolver interface provides a 100 mA reference current at 8 kHz and 2.8 Vrms, which the controller interpolates to a resolution of 14 bits. Command inputs through step-direction lines can be processed at up to 2 MHz. The resolver channel supports applications that need absolute shaft information at power-up, while the step-direction input lets the module accept commands from indexers or motion controllers.
