Product Description:
The BEL-090-14 is a digital servo drive module produced by Copley Controls for the Accelnet CanOPEN Modules series. It regulates current and velocity for brushless or stepper axes, linking motion controllers to motors in automated machinery and conveying systems. By combining power electronics with fieldbus and analog command paths, the unit streamlines axis integration inside multi-drive industrial panels.
For torque control it can deliver a continuous phase current of 7 Adc and momentarily raise output to 14 Adc for loads that last up to 1 s. The current loop is refreshed every 16 kHz, while the velocity/position loop updates at 4 kHz; these cycle times allow tight regulation even on low-inductance windings, which the drive supports down to 200 µH line-to-line. A DC bus between 14 Vdc and 90 Vdc supplies the stage, and power events are captured by internal logic that samples the ±10 Vdc, 12-bit analog reference input. Eleven opto-isolated digital inputs can gate motion, home axes, or change operating modes during sequence execution.
Command and feedback bandwidth complement the current handling capability. The encoder channel accepts position data at up to 8 Mcount/s, and stepper style pulse-direction commands are processed at a ceiling of 2 MHz. Networked communication occurs over EtherCAT, with an RS-232 port reserved for commissioning. The supply corridor is bounded by a maximum of 90 Vdc and a minimum of 14 Vdc, allowing the same drive to run on battery or rectified mains rails. Mechanical size without a heatsink is 129 × 86.6 × 50.4 mm; adding the factory heatsink extends depth to 86.1 mm, giving installers a consistent footprint whether convection or forced-air cooling is chosen.
