Multi-axis DC servo drive with choice of connectivity

Each axis is configurable to drive a stepper, brushless, or brushed DC motor. Using advanced FPGA technology, this capability provides a significant reduction in the cost per node by combining stepper and servo motors into a compact multi-axis package. Each axis in these Multinet drives operate as an EtherCAT node under DSP-402 or a CANopen node under CiA-402 for motion control devices.

Supported modes include: Cyclic position/velocity/torque, Profile Position-Velocity, Interpolated Position Mode (PVT), and homing. Servo mode of steppers allows position/velocity/torque control. Servo mode allows CANopen or EtherCAT or digital PWM control of position/velocity/torque. In microstepping mode stepper command pulses and master encoder for camming or gearing is supported.

High-speed digital inputs with programmable functions are provided and the outputs are 24V compatible. An SPI port is provided with one high-speed input and four high-speed digital outputs. If not used for SPI, the input and outputs are programmable for other functions.

An RS232 serial port provides a connection to Copley's CME2 software for commissioning, firmware upgrading, and saving configurations to flash memory. The EtherCAT port is magnetically isolated and the CANopen port is optically isolated.

Drive power is transformer-isolated DC from regulated or unregulated power supplies. An AuxHV input is provided for "keep-aliv" operation permitting the drive power stage to be completely powered down without losing position information, or communications with the control system.
