STMicroelectronics STEVAL-ETH001V1 Servo Drive Evaluation Board
STMicroelectronics STEVAL-ETH001V1 Servo Drive Evaluation Board is designed to address three-phase PMSM applications oriented to multi-axial position control and connectivity. The STEVAL-ETH001V1 Evaluation Board embeds a motor control power stage, a digital actuation section, and a power management section.
The motor control power stage hosts the STDRIVE101 half-bridge gate driver and six STH270N8F7-2 power MOSFETs, featuring real-time connectivity with Ethercat communication protocol supported by the NETX90 network controller. In contrast, the digital actuation section hosts an industrial IO management section with CLT03-2Q3 (input) and IPS160H (output). L7987, L7805CD2T-TR, and LD39150DT33-R devices power the power management section.
The STM STEVAL-ETH001V1 Evaluation Board is equipped with two RJ45 connectors for daisy chain connection and an RS485 interface for digital encoder or host connection powered by ST3485EI. For 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 an index is also included.
