Product Description:

The BE2-090-14-H is a two-axis servo amplifier module manufactured by Copley Controls within the Accelnet CANopen Modules series. Designed for distributed motion systems on a CANopen network, the unit interfaces between higher-level motion controllers and brushless or stepper motors, regulating phase current and position feedback for compact machines or OEM sub-assemblies. By placing drive intelligence close to the motor, the module reduces panel wiring and supports deterministic axis coordination in packaging, semiconductor, and material-handling equipment.

Each axis delivers 7 Adc continuously and can surge to 14 Adc for up to 1 s, providing headroom for acceleration phases. The digital PWM current loop runs at 16 kHz, while the servo update for velocity and position executes at 4 kHz to maintain low latency. A 12-bit analog reference permits fine torque or velocity control, and the controller can accept step-and-direction commands at a maximum rate of 2 MHz for high-resolution indexers. Encoders are supported up to a 5 MHz line frequency and receive 5 V at 500 mA from the onboard supply, eliminating the need for an external sensor supply. The design also requires a minimum load inductance of 200 µH to limit ripple current in low-impedance windings.

The module accepts a high-voltage input range from 14 Vdc to 90 Vdc, allowing it to share supplies with battery-backed or rectified mains buses. When the internal heat sink temperature reaches 70 °C, an overtemperature trip disables power to protect the semiconductors. PWM outputs honor a minimum pulse width of 220 ns so that switching edges remain within dead-time limits. The metal enclosure measures 6.78 × 4.70 × 3.14 in and weighs 2.75 lb, enabling cabinet or machine-mounted installation without heavy support. Field wiring is simplified by CANopen communication, while encoder feedback, analog command lines, and high-frequency step sequences are handled within the module’s two-axis design.
