Product Description:

The 800-1579E is a DC-bus servo drive module produced by Copley Controls for the Accelnet CANopen Modules series. Intended for integration into distributed motion platforms, the module converts CANopen network commands into regulated phase currents that actuate brushless or brushed motors in automated pick-and-place units, indexing tables, and similar equipment. By housing the power stage, controller, and network interface in a single enclosure, the unit simplifies cabinet wiring in industrial automation cells.

The drive has a continuous current capability of 6 Adc, allowing it to sustain 533 W of mechanical shaft power. For brief overloads, it delivers a peak current of 12 Adc and a peak power output of 1600 W for up to 1 s. These operating margins allow machines to accelerate quickly without exceeding the drive’s thermal limits. Bus protection shuts down the power stage above 91 VDC or below 14 VDC. The connected motor must provide at least 200 µH of inductance to keep current ripple within acceptable limits and prevent regenerative surges. The aluminum chassis measures 97.28 × 62.74 × 32.77 mm, allowing the module to be mounted beside other drives in compact installations. Nine optically isolated inputs and four outputs accommodate limit switches, drive-ready signals, and sequence control.

The current regulator operates at 15 kHz, while the PWM ripple frequency is 30 kHz. The command interpreter processes step-and-direction pulses at rates up to 2 MHz and follows velocity or position updates at 3 kHz. The analog command port has an impedance of 5.36 kΩ, which minimizes the load placed on external signal sources. An internal sensor shuts down the drive at 70 °C to protect its power devices from excessive heat. Fault conditions are reported through the programmable digital outputs. Fast internal processing supports the available command rates and helps keep trajectory errors small when the host controller sends closely spaced updates.
