Overview
The
has been developed for motor control applications and multi-axial position control in
factory automation applications.
The board is characterized by a 6-layer stack structure for a better noise immunity and features:
•
Ethernet real-time communication with on-board EtherCAT protocol
•
Three-phase motor driver inverter based on
•
®
32-bit Cortex
®
-M7
•
NETX90 network controller
•
Operating supply voltage up to 48 V with a max. overvoltage robustness of 60 V
•
Max. power dissipation up to 700 W
•
Motor brake dissipative energy circuit
•
Digital actuation section for industrial loads
•
RS485 interface for digital encoder and host interface
•
On-board DC-DC converter and linear regulator
The
has a compact form factor to facilitate engine assembly. The board structure can be
schematized as shown below.
