Copley Accelnet R22

Accelnet R22 is a ruggedized, PC board-mounting digital servo drive that combines CANopen networking with 100% digital control of brush or brushless motors. It operates as a Motion Control Device using the DSP-402 protocol under the CANopen DS-301 V4.01 (EN 50325-4) application layer. DSP-402 modes supported include Interpolated Position (PVT), Profile Position, Profile Velocity, Profile Torque, and Homing. A ±10 Vdc analog input has been added for position/velocity/torque control.

Ten logic inputs are configurable as CAN address bits, enables, limit & home switches, motor temperature switch, stepper/encoder pulses, and reset. Two logic outputs are programmable to report drive status, or to drive a motor brake. As a stand-alone drive Accelnet R22 can operate using incremental position commands from step-motor controllers in Pls/Dir or CW/CCW format, as well as A/B quadrature commands from a master-encoder. Drive commissioning is facilitated by CME 2™ software operating under Windows® communicating with Accelnet R22 via an RS-232 link. Auto-tuning algorithms in CME 2™ slash set up times for fast system commissioning by automating motor phasing, and current-loop tuning.

A powerful oscilloscope and waveform generator display drive performance for fine tuning. Drive configurations are saved in non-volatile flash memory. OEM’s can inventory one part, and configure drives on-site to each axis in a machine. All drive circuits are DC coupled and operate from unregulated transformer-isolated linear DC power supplies, or regulated switching power supplies. The pc-board mounting package is suitable for high-density, multi-axis installations in equipment where space is at a premium, and wiring must be minimized.
