The Accelnet CANopen Modules series is a family of DC-powered digital servo drives from Copley Controls designed for position, velocity, and torque control of brushless and brush motors in compact machine-integrated installations.
Across the series, the drives operate as CANopen motion-control devices using DSP-402/CiA 402 profiles and support functions such as profile position, profile velocity, profile torque, interpolated position, homing, camming, gearing, and point-to-point indexing. The platform also supports multiple command methods beyond the CANopen network, including ±10 V analog references, PWM commands, step-and-direction or CW/CCW pulse inputs, discrete I/O, and master-encoder inputs for geared or cammed motion. Feedback support varies by version but includes digital quadrature encoders, digital Hall sensors, and, on selected models, resolver, sin/cos, secondary encoder, and absolute encoder capability. The series is built around fully digital current, velocity, and position control loops, with configurable digital I/O, RS-232 commissioning support, flash-based parameter storage, and optional keep-alive power inputs that preserve communication and position information when the power stage is shut down.
