Product Description:
The ACJ-090-12 is a digital servo drive module produced by Copley Controls within the Accelnet CANopen Modules series. It converts a regulated DC bus into two-quadrant current for brushless and brushed motors, while a CANopen interface links the drive to motion controllers in distributed automation lines. By combining power transistors, signal processing, and network communication in a 97.28 × 62.74 × 32.77 mm housing, the unit saves panel space and allows placement near the actuator to shorten motor leads.
The drive can deliver a continuous phase current of 6 A DC, providing a continuous mechanical output of 533 W when the bus voltage and motor constants are matched. The current and velocity loops are refreshed at 15 kHz and 3 kHz, respectively, providing tight control of torque and speed. Motor windings must provide at least 200 µH of inductance to prevent saturation from the PWM edges. The internal output stage has 0.075 Ω of resistance, which determines copper loss at the rated current. Thermal protection is triggered at an enclosure temperature of 70 °C, while an overvoltage trip at 91 V DC protects the bus capacitors. The encoder interface supplies +5 V DC at 400 mA for incremental or commutation feedback, and it counts quadrature transitions up to 20 MHz so high-resolution encoders remain usable at elevated speeds.
During acceleration or shock loading, the module supplies a peak current of 12 A DC, allowing up to 1600 W of electrical output for bursts lasting 1 s. A carrier switching scheme centered on 30 kHz minimizes audible noise and keeps motor ripple torque low without exceeding the minimum load inductance. The drive weighs 0.14 kg, reducing mass on moving carriages when it is mounted directly on an axis. Its compact housing permits installation in gantry, packaging, and indexing equipment that requires precise and rapid current modulation.
