Internal Product Review
The BE2-090-14-R is a Copley Controls Accelnet CanOPEN module built for precise motion control in compact automation systems. A 14 to 90 Vdc bus range and 7 Adc continuous current give the module strong application flexibility and steady drive performance. A 14 Adc peak current for 1 s supports responsive acceleration, making the BE2-090-14-R a very capable choice for dynamic axes.

Product Description:
The BE2-090-14-R is a compact DC drive module manufactured by Copley Controls for the Accelnet CANopen Modules series. Designed for decentralized motion systems, it converts a regulated DC bus into phase-modulated power that drives servo or stepper motors while exchanging control data over a CANopen network. The unit delivers closed-loop torque, velocity, or position control without burdening the main controller with high-frequency current regulation tasks.
The power stage accepts a bus voltage from 14 Vdc through 90 Vdc, allowing operation with high-energy supplies as well as battery sources. Under continuous load, it delivers 7 Adc, and it can surge to 14 Adc for acceleration or disturbance recovery during a 1 s peak interval. A brake output rated at 1.0 Adc supports a dynamic-brake resistor, and an opto-isolated output sources 300 mAdc for external relays. The minimum load inductance is 200 µH, preventing excessive ripple when the PWM stage switches. Protection is provided by a 70 °C drive over-temperature trip that removes gate signals before the silicon reaches its thermal limit. An encoder interface supplies 5 Vdc at 500 mA to power differential line drivers, ensuring clean feedback over long cables. The analog command inputs have an input impedance of 5.05 kΩ, so upstream sources are only lightly loaded.
The current loop executes at 16 kHz to regulate phase current, while the velocity and position loops run at 4 kHz to correct trajectory errors. Stepper motors can be commanded through pulse-direction inputs at frequencies up to 2 MHz. The PWM hardware supports a minimum pulse width of 220 ns, allowing precise duty-cycle control during rapid switching. The discrete outputs use the same update scheduler as the motion loops, keeping connected actuators synchronized with axis commands.
