Product Description:

The AEP-090-36 servo drive module is produced by Copley Controls for the Accelnet Plus EtherCAT servo drive family. It operates as a compact, panel-mounted amplifier that links motion controllers to brushless or brushed servo motors over an EtherCAT network. The module regulates motor phase current and closes velocity and position loops to support precise motion in industrial automation cells. Its compact design suits positioning axes, material-handling equipment, assembly systems, and other applications that require coordinated motor control.

The drive can deliver a continuous output current of 12 A DC and a peak output current of 36 A DC for rapid acceleration. The peak current can be maintained for 1 s before the drive returns to its continuous rating. Pulse-width modulation occurs at 16 kHz, helping reduce audible motor noise and produce smooth current control. The velocity and position control loops update at 4 kHz to maintain accurate response to changing commands and loads. An output resistance of 0.036 Ω helps limit conduction losses in the power stage. The controller provides eight optically isolated digital inputs and three digital outputs for limit switches, drive enables, and fault signals. Power-stage current ripple occurs at a frequency of 32 kHz. Two RJ45 EtherCAT connectors support pass-through network wiring between multiple drives.

The physical package measures 196 × 99 × 31 mm, allowing several modules to fit into a space-conscious control cabinet. Quadrature encoder feedback is accepted at rates up to 20 Mcounts/s, supporting high-resolution position measurement during rapid motion. A regulated 5 V DC encoder supply with ±2% tolerance powers the connected feedback sensor. The command interface accepts an analog reference of ±10 V DC for stand-alone torque or velocity operation. A galvanically isolated input path protects upstream control equipment from unwanted electrical potential differences. The connected motor must have a minimum inductance of 200 µH to maintain stable current regulation and keep the rate of current change within the controller’s operating limits.
