Product Description:
The XSJ-230-10-S is a compact drive module produced by Copley Controls as part of the XENUS Digital Loop Modules series. Designed for installation in multi-axis machinery, the module closes current and position loops for brushless servo or stepper motors. By translating high-speed command pulses and analog references into timed PWM outputs, it serves as a key interface between the machine controller and the motor windings in automated assembly, inspection, and material-handling stations.
During continuous operation, the drive can deliver 5 A DC of motor phase current while handling transients up to 10 A DC without saturating its power stage. A digital current loop running at 15 kHz supervises these outputs, synchronizing with the internal PWM carrier to maintain torque linearity. Pulse-and-direction inputs are accepted at rates as high as 1.5 MHz, allowing microstepped positioning from high-resolution motion controllers. The analog front end samples reference voltages with a 12-bit converter, so torque or velocity commands retain fine scaling. Brake coils are energized through a dedicated 1 A DC transistor output, and the hardware remains stable with low-inductance loads due to edge-aligned switching. The 126 × 89 × 53 mm enclosure mounts to a grounded heat spreader for thermal conduction.
The encoder interface processes sine-cosine feedback up to 230 kHz, interpolating each electrical cycle by 10 bits to enhance position fidelity. Signals are accepted at 1.0 Vpp differential levels, and the module powers the transducer through a regulated 5 V DC, 250 mA rail. For ironless motors or high-bandwidth linear stages, the current stage tolerates phase inductance as low as 200 µH while keeping ripple within the 30 kHz sideband of its PWM. Excess mechanical energy is redirected to the DC bus through a regenerative section rated for a peak of 80 W, so braking events do not cause supply overvoltage.
