Getting started with the low voltage servo drive for multi-axial position control with
Introduction
The
STEVAL-ETH001V1
servo drive evaluation board has been developed to address three-phase PMSM applications oriented
to multi-axial position control and connectivity.
Motor control power stage hosts the
allows multi-axial position control for PMSM motor, featuring real-time connectivity with EtherCAT stack available on-board.
Moreover, load actuation and interface based on
Proper board functionality is supported by a power management unit based on L7987L,
devices.
The
STEVAL-ETH001V1
is equipped with two RJ45 connectors to guarantee daisy-chain connection and a stripline connector to
interface via RS485 digital encoder or host unit (i.e., a PC). For a better noise immunity, the PCB is characterized by a 6-layer
stack and an insulated track for supply line and ground. A quadrature encoder interface with index is present as well.
