Product Description:

The 800-1843 servo drive is produced by Copley Controls and belongs to the Accelnet CANopen Modules series. It functions as a decentralized amplifier that converts CANopen motion commands into high-speed pulse-width modulated energy for brushless or brushed motors used in automated gantries, pick-and-place heads, and precision conveyors. By placing the regulation electronics close to the motor, the module decreases wiring length, improves noise immunity, and simplifies multi-axis architectures in industrial automation.

For analog reference processing, the drive presents an input impedance of 5.05 kΩ and samples each channel with a 12-bit converter that provides 4,096 discrete counts. Torque is corrected by a current loop that updates at 16 kHz, supporting stable operation with load inductances as low as 200 µH. The power stage supports a minimum pulse width of 220 ns, while differential receivers track incremental encoder signals at frequencies up to 5 MHz without losing pulses. When a pulse-train interface is used, the step input accepts rates up to 2 MHz. Host-driven velocity or position targets can be refreshed at 4 kHz to accommodate complex motion trajectories.

Machine-level interaction is handled by 11 optically isolated digital inputs and 4 sourcing digital outputs that report faults or position-reached events. The drive can provide controllers with an emulated quadrature signal at a resolution of 4,096 lines per revolution, allowing legacy hardware to read servo position directly. A regulated encoder supply provides up to 500 mA at +5 VDC for external sensors. The unit measures 1.99 inches deep, 3.41 inches high, and 5.08 inches wide, permitting dense cabinet installation without separate heat sinks. Its digital input and output channels support direct connections to machine sensors, switches, indicators, and control devices. The encoder interface also allows the drive to communicate position data to equipment that requires a conventional quadrature feedback signal.
