Product Description:
The 800-2122 is a compact DC servo drive module manufactured by Copley Controls within the Accelnet CANopen Modules series. It converts a low-voltage DC bus into controlled three-phase power for a single motor, so the module controls one axis. By mounting directly on a DIN rail behind a machine panel, the drive supplies synchronized current and velocity commands to motors used in pick-and-place arms, conveyors, and other automated equipment.
Motion and feedback resources include one analog input with 12-bit resolution, giving the controller fine discrimination of reference voltages. During continuous operation, the power stage delivers 3 A RMS per phase, while the motor bus can operate at up to 90 VDC, enabling high-speed responses from compact motors. Carrier modulation supports fundamental output frequencies up to 3900 Hz, allowing the drive to operate low-inductance windings without audible torque ripple. For short transients, the current limit rises to 6 A, allowing rapid acceleration before thermal limits intervene. The peak current is available for 1 second, a duration coordinated with internal sensing to prevent an overload. Communication and diagnostic connections include an RS-232 serial port and two EtherCAT ports with RJ45 sockets, simplifying daisy-chain network layouts.
Machine-level I/O is handled through 11 optically isolated digital inputs and 4 sourcing outputs, allowing the drive to process limit-switch signals, enable commands, and fault-reset requests without additional PLC cards. The electronics are housed in an IP20 enclosure suited for installation inside a protected cabinet with adequate convection cooling. Power is drawn from a DC supply with an operating range that begins at 14 VDC and extends to 90 VDC, making the module compatible with battery systems and regulated supplies on mobile or stationary platforms. Vector-control algorithms manage commutation through field-oriented operation, while internal protection circuitry monitors overcurrent, excessive temperature, and drive faults during each operating cycle.
