Board application
The board enables the application design of a speed controlled closed-loop
motor control drive profile synchronized over a Real-time Ethernet based
industrial commination protocol. It serves as example for an FOC based
motor control system design with network connectivity using the netX 90
multiprotocol SoC with built-in motor control features.
The motor supply voltage is at the same the power supply for the NXHX 90-
MC board. The integrated DC/DC converter of the 3-Phase Gate Driver IC,
with a wide voltage input range from 12V to 43V (36V +20%), generates the
3.3V single supply for the netX 90. For operating the NXHX 90-MC board,
the nominal input voltage range is +12V to 36V DC for either 12V, 24V or
36V motor supply voltages with 24V the most popular for industrial
applications.

In order to facilitate the interconnection of industrial motors with integrated
quadrature encoders, Hilscher offers an NXHX-DH adapter accessory card
for the NXHX 90-MC board. It contains push-in connectors for up to two
quadrature encoders and three digital hall sensors. The NXHX-DH board
converts RS-422 (5V differential) and TTL (5V single-ended) quadrature
encoder signals to 3.3V inputs for the NXHX 90-MC board and provides a
5V supply for the encoders. Additionally, it contains analog filters for the
digital hall inputs.
