Copley Controls: Accelnet Plus Module, 1-Axis (APM Series)
14-90V VDC CANopen Drives for Brushless Motors
Accelnet APM is a high-performance, DC powered servo drive for position, velocity, and torque control of brushless and brush motors via CANopen. Using advanced FPGA technology, the APM provides a significant reduction in the cost per node in multi-axis CANopen systems.
The APM operates as an CANopen node using the CANopen over CANopen (CoE) protocol of DSP-402 for motion control devices. Supported modes include: Profile Position-Velocity-Torque, Interpolated Position Mode (PVT), and Homing. Command sources also include ±10V analog torque/velocity/ position, PWM torque/velocity, and stepper command pulses.
Feedback from a number of incremental and absolute encoders is supported.
Nine high-speed digital inputs with programmable functions are provided, and a low-speed input for motor temperature switches.
An SLI (Switch & LED Interface) function is supported by another high-speed input and four high-speed digital outputs. If not used for SLI, the input and outputs are programmable for other functions. Two open-drain MOSFET outputs can drive loads powered up to 24 Vdc.
An RS-232 serial port provides a connection to Copley’s CME2 software for commissioning, firmware upgrading, and saving configurations to flash memory.
Drive power is transformer-isolated DC from regulated or unregulated power supplies. An AuxHV input is provided for “keep-alive” operation permitting the drive power stage to be completely powered down without losing position information, or communications with the control system.
