DC motor control Stepnet SE2 series

stepperdual-axistorque control

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 multi-axis EtherCAT systems. Each of the two drives in the SE2 operates as an EtherCAT slave using the CAN application layer over EtherCAT (CoE) protocol of DS-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, and torque. In microstepping mode, stepper command pulses and master encoder for camming or gearing are supported. Twenty-three high-speed digital inputs with programmable functions are provided with two low-speed inputs for motor temperature switches.
