AEP-180-09 by Copley Controls

The Copley Controls AEP-180-09 is a compact servo drive within the Accelnet CanOPEN Modules series, designed to deliver precise motion control in industrial automation applications. This module operates at 180 Vdc and provides a continuous current rating of 3 Adc (2.1 Arms-sine), making it suitable for medium-duty servo motor applications. Measuring only 196.3 mm x 99.1 mm x 29.7 mm, the AEP-180-09 achieves a small footprint without compromising performance. Its primary function is to regulate and drive three-phase brushless or permanent-magnet servo motors, enabling accurate positioning and speed control in robotics, CNC machines, and automated assembly systems.

Incorporating advanced power electronics, the AEP-180-09 features a 3-phase MOSFET inverter with a PWM frequency of 16 kHz for smooth current modulation and reduced motor cogging. The drive supports 8 opto-isolated digital inputs and 3 opto-isolated digital outputs, ensuring robust signal integrity and protection against electrical noise. Encoder feedback is powered by an internal +5 Vdc supply (±2% tolerance at up to 400 mAdc), facilitating high-resolution motor commutation. The module handles short-term current peaks of 9 Adc (6.4 Arms-sine), providing ample headroom for rapid acceleration and deceleration events. Cooling is achieved through a combination of heat sink and/or forced air cooling, optimizing thermal management under continuous or burst operation.

Engineered for reliability, the AEP-180-09 operates over an ambient temperature range of 0 to +45 °C and can be stored between -40 to +85 °C without performance degradation. Weighing just 1.0 lb (0.45 kg), this lightweight drive enhances system efficiency and simplifies installation. Its robust design ensures compatibility with standard CanOPEN networks and common servo motors, while the opto-isolated I/O interfaces protect control electronics from voltage transients. By delivering precise current regulation and efficient heat dissipation, the AEP-180-09 reduces mechanical wear, minimizes maintenance downtime, and extends the service life of industrial machinery, ultimately improving throughput and reliability across diverse automation environments.
