Copley Controls: Accelnet Plus Module, 1-Axis (AEM Series)

14-90V VDC EtherCAT Drives for Brushless Motors


Description

Accelnet Plus AEM is a high-performance, DC powered servo drive for position, velocity, and torque control of brushless and brush motors via EtherCAT, an Ethernet-based fieldbus. Using advanced FPGA technology, the AEM provides a significant reduction in the cost per node in multi-axis EtherCAT systems.

The AEM operates as an EtherCAT slave using the CAN application layer over EtherCAT (CoE) protocol of DSP-402 for motion control devices. Supported modes include: Cyclic Synchronous Position-Velocity-Torque, Profile Position-Velocity-Torque, Interpolated Position Mode (PVT), and Homing.

Command sources also include ±10V analog torque/velocity/position, PWM velocity/torque, 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.
