Product Description:

The 800-1811 is a multi-axis digital drive module produced by Copley Controls for the Accelnet CANopen Modules series. Designed for distributed motion systems, the unit interfaces with CANopen networks to supply current-mode control to brushed or brushless servomotors. By combining bus power conversion, current regulation, and fieldbus communication, the module simplifies cabinet wiring in industrial automation cells that require synchronized axis performance.

A regulated bus voltage of 90 VDC feeds the power stage, enabling the drive to deliver energy to connected motors. Each axis produces a continuous motor current of 7 ADC per axis. During acceleration, the current can rise to 14 ADC for one second, while the common input carries peak current of 28 ADC and continuous current of 14 ADC. The internal current loop is updated at 16 kHz to maintain low torque ripple and stable motor response. For host communication, an EtherCAT expansion is available through a dual RJ-45 100BASE-TX port, permitting fast diagnostic access without disturbing the primary CANopen command path. The protection thresholds include an overvoltage limit that matches the bus level and an undervoltage trip at +14 VDC. Thermal shutdown activates at 70 °C to prevent semiconductor overstress during operation.

Motors with at least 200 µH of phase inductance remain within the controller’s stability limits. The velocity and position loops execute at 4 kHz, providing tight following-error control for precise positioning. The aluminum chassis measures 172.1 × 119.3 × 44.1 mm, allowing side-by-side rack installation without requiring excessive panel space. Its mass of 0.68 kg reduces the load on moving machine subplates where weight is important. Integrated undervoltage, overvoltage, peak-time, and thermal protections help prevent operation outside the permitted electrical and temperature limits.
