Product Description:
The 800-1720 drive module is produced by Copley Controls within the Accelnet CANopen Modules series. As a compact digital servo amplifier, it connects to higher-level motion controllers through a CANopen interface and regulates phase current for brushless or brushed servo motors in pick-and-place heads, electronics assembly machines, and other precision axes. It translates network commands into controlled motor torque for accurate industrial positioning. The compact module format supports installation near the controlled axis, which can shorten motor wiring and reduce the amount of cabinet space required for the motion system.
For continuous duty, the amplifier delivers 3 A of motor current and provides 0.15 kW of electrical output to the load under sustained operating conditions. Demanding moves can be handled with a surge of 6 A that the unit sustains for up to 1 s, raising the available output to 0.33 kW before foldback protection engages. The input bus must provide 3.3 A continuously and 6.6 A at peak demand, allowing the power supply to be sized with an appropriate operating margin. Position and velocity commands are processed at a 3 kHz update rate, helping keep path errors low for medium-speed axes. The current-controlled H-bridge operates within these limits while maintaining loop stability and preventing excessive motor temperatures.
The CAN interface transmits at 1 Mbit/s, supplying command and status data with minimal latency. Inside the drive, the current loop has a bandwidth of 2.5 kHz, and its digital regulator updates at 15 kHz to track reference currents accurately. Pulse-width modulation switches at 30 kHz, reducing audible noise and smoothing torque delivery. Ten digital inputs accept limit, home, or user signals, while three digital outputs can sink 300 mA for brake release or relay logic. The module has a mass of 0.037 kg, making it suitable for mobile equipment and machinery with restricted installation space. Its combination of network communication, digital input and output channels, and fast internal control loops supports coordinated motion without requiring a separate interface module.
