ST STEVAL-ETH001V1 User manual

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 STDRIVE101 half bridge gate driver and six STH270N8F7-2 power MOSFETs. The solution
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 RS485 are possible using CLT03-2Q3, IPS160H and ST3485EI ICs.
Proper board functionality is supported by a power management unit based on L7987L, L7805CD2T-TR and LD39150DT33-R
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.

2.2 Motor driver
The motor driver consists of a three-half bridge with the STH270N8F7-2 power MOSFET driven by the
STDRIVE101 gate driver to drive a three-phase motor embedding quadrature encoder to detect the rotor position.
The STDRIVE101 embeds different blocks mainly featuring:
1. Matched propagation delay for all channels
2. Very short propagation delay of 40 ns
3. Integrated bootstrap diodes
4. 12 V LDO linear regulator (50 mA max.)
5. Embedded VDS monitor for each external MOSFET
6. Overcurrent comparator
7. UVLO and thermal shutdown protection
8. Standby mode for low current consumption operation
Motor driving signals are modulated according to the current sensing and speed feedback.
The sensing network has been built using the TSV991ILT operational amplifier which amplifies the voltage signal
read by three shunt resistors connected in series to each STH270N8F7-2 power MOSFET low side.

To limit overvoltage during motor active braking operation, the use of an external brake resistor is supported,
dissipating the motor avalanche energy. It is suggested to connect two resistors (10 Ω 25 W) in parallel with J4
screw connector.

2.3 Serial interface
The on-board RS485 interface connects the digital absolute encoder based on EnDat, BiSS, and SSi, or
establishes PC communication using a standard serial terminal.
The interface consists of two RS485 (one for the data and one for the clock) based on ST3485EI.
Using J12 jumper, it is possible to select between 5 V and 3.3 V as supply voltage of the digital absolute encoder
connected via U18 connector.

2.4 Digital actuation
The circuit implements an actuation power stage, with two digital input channels and two digital output channels;
the digital output allows driving any kind of load (inductive , resistive, and capacitive), guaranteeing a 2.5 A output
current.
Thanks to the integrated active clamp on the IPS160H IC, it is possible to manage demagnetization energy
without any external component, whereas embedded protection in the intelligent power switch provides
robustness against:
1. cut-off and thermal shut-down
2. overcurrent with 2.6 A minimum threshold
3. undervoltage lock-out
4. Vcc disconnection
The diagnostic feature is also available with a dedicated pin to signal:
1. cut-off intervention
2. thermal shut-down intervention
3. open load in off state
The feedback related to load driving can be implemented using the IC CLT03-2Q3 current limiter; in this case, it is
necessary to connect the IPS160H output to the current limiter input stage.

2.5 Power management
The power stage circuit consists of an input stage with 48 V max. operating voltage and 60 V max. overvoltage,
embedding two 330µF/100V electrolytic bulk capacitors with Transil protection, and two DC-DC converters in buck
configuration to regulate the 3.8 V and the 15 V.
The 3.8 V regulates the 3.3 V with max. output current of 1 A for the digital circuit ( i.e. microcontroller, ST3485EI
transceiver, NETX90); the 15 V is used, instead, for the STDRIVE101 digital supply and to regulate the 5 V with
200 mA output current supplying the encoder.
Both regulation circuits have been built using the L7987L switching regulator in TSSOP package. Two linear
regulators have been inserted in series into the switching regulator to improve the ripple on the regulated low
voltage reference (3.3 V and 5 V): in particular, the LD39150DT33-R low drop has been used for the 3.3 V and
the L7805CD2T-TR linear regulator has been used for the 5 V.

2.6 Ethernet real-time connectivity
The connectivity core is the NETX90 multi-protocol SoC which integrates two PHYs with 100 Mbps
communication speed, powered by a dual core structure and several peripherals, such as SPI,USART,I2C, CAN,
FMC, ADC and timers.
Communication peripherals (such as SPI and FMC) manage the communication between the controller and the
MCU (feature implemented by dedicated libraries that have been developed by the controller manufacturer).
Other peripherals, such as EnDat2.2 , BiSS and SSi, interface the controller with the encoder in motor control
applications (the related libraries are not implemented at the moment).
The network controller for this application solution is programmed with the EtherCAT protocol, enabling a
communication with low latency and low jitter between master node and slave node.
The protocol stack and the firmware library for STM32 have been developed in demo version by the controller
manufacturer (Hilscher) and are integrated into the application and middleware layers of the STEVAL-ETH001V1
evaluation board.
Daisy-chain communication can be implemented thanks to the two on-board RJ45 connectors.
