Copley Controls: Stepnet Plus Module, 2-Axis (SE2 Series)
14-90V VDC EtherCAT Drive for Stepper Motors
Description
Stepnet SE2 is a dual-axis, high-performance, DC powered drive for position, velocity, and torque control of stepper motors via EtherCAT, an Ethernet-based fieldbus. Using advanced FPGA technology, the SE2 provides a significant reduction in the cost per node in multiaxis EtherCAT systems.
Each of the two drives in the SE2 operate as an EtherCAT slave using the CAN application layer over EtherCAT (CoE) protocol of DSP-402 for motion control devices. Supported modes include: Profile Position-Velocity, Cyclic Synchronous Position-Velocity, Interpolated Position Mode (PVT), and Homing. Servo mode allows ±10V analog or digital PWM control of position/velocity/torque. In microstepping mode stepper command pulses and master encoder for camming or gearing is supported.
Twenty-three high-speed digital inputs with programmable functions are provided, and two low-speed inputs 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. Three open-drain MOSFET 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.
