Product Description:

The 800-1656 is a DC-powered servo drive module manufactured by Copley Controls for the Accelnet CANopen Modules series. It regulates motor torque, velocity, and position through CANopen commands, allowing machine builders to integrate precise motion axes without dedicated analog interfaces. By closing current and velocity loops inside the drive, the unit offloads real-time processing from the system controller and supports tightly coordinated moves in industrial automation cells.

The drive operates from a bus of 90 VDC and can deliver a continuous phase current of 6 ADC, providing a sustained mechanical output of 0.53 kW. The drive provides 12 opto-isolated inputs that allow direct connection to limit switches or index sensors and support rapid sampling for deterministic events. Its 3 sourcing outputs transmit drive status to external relays or indicators. A current-loop update rate of 15 kHz works with an output resistance of 0.075 Ω to keep motor current ripple low. The minimum permissible load inductance is 200 µH, preventing excessive current change during switching. Position feedback can be accepted from incremental encoders at frequencies up to 5 MHz or from step commands presented at 2 MHz. The package measures 168 × 99 × 31 mm, making the unit suitable for dense multi-axis panels.

For transient moves, the controller supports a peak current of 18 ADC and a surge power of 1.55 kW for up to 1 second before returning to its continuous limits. Pulse-width modulation is generated at 15 kHz, aligning with the current-loop rate to minimize beat frequencies. A velocity loop that closes at 3 kHz allows rapid speed corrections during load changes. The step-command interface and encoder bandwidth support responsive position control across demanding motion profiles. The low 0.075 Ω output impedance helps translate dynamic torque commands into shaft motion without excessive phase lag.
