Product Description:

The AEP-055-18 is a servo drive module produced by Copley Controls as part of the Accelnet CANopen Modules series. It mounts inside control cabinets and interfaces with motion controllers over the CANopen fieldbus to regulate current, velocity, and position for brushless or brushed DC motors used in automated assembly, packaging, and material-handling equipment. By combining power electronics with onboard signal processing, the module provides precise motor actuation from a compact footprint without requiring a separate external amplifier.

The drive supplies a continuous output of 6 A DC and can deliver up to 18 A DC for acceleration, with peak output limited to 1 s to protect the power stage. Current regulation operates at 16 kHz, providing a 2.5 kHz bandwidth for rapid torque corrections, while the velocity loop updates at 4 kHz to stabilize speed under varying loads. The minimum load inductance is 200 µH, and the output resistance is 0.075 Ω; both parameters influence current ripple and control-loop stability. Eight optically isolated digital inputs accommodate limit, home, and inhibit functions, while three digital outputs report operating status to the master controller. A six-position, four-contact RJ-11 connector provides an RS-232 service port for configuration and diagnostics.

Up to 55 V DC can be applied to the DC bus, and the power stage switches this supply at a PWM frequency of 32 kHz to reduce audible noise and harmonic heating. The feedback interface handles encoder data rates of up to 20 million counts per second, supporting high-resolution position control at elevated motor speeds. The aluminum enclosure measures 196 × 99 × 31 mm, allowing multiple modules to be installed side by side in shallow control panels. Its compact enclosure also helps preserve space for power distribution, communication wiring, and other motion-control components within the cabinet.
