Many original equipment manufacturers (OEMs) have become accustomed to relying on field-programmable gate array (FPGA) or ASIC technology to complement features not supported by off-the-shelf products.
One of these functions is to interface with position sensors in industrial servos and AC inverter drives. Using FPGAs and ASICs to support position sensor feedback increases system cost and adds unnecessary development complexity. Because of this latest feature, developers must spend extra time and effort writing complex code instead of focusing on product differentiation and the core's capabilities in motor control and motion control. In addition, both FPGAs and ASICs offer a relatively fixed implementation that lacks scalability in multiple applications without redesigning.
If there is a solution that simplifies the system, saves board space and development effort, and eliminates the need for developers to make unnecessary investments in non-differentiated feature development in the industry, what happens?
By using the C2000TM DelfinoTM TMS320F28379D/S MCU and DesignDRIVE Location Manager technology, designers can avoid this problem and interface directly with position sensors.
When combining DesignDRIVE position manager technology with the new Delfino F28379 MCU, an industrial drive system-on-a-chip (SoC) solution can be created to achieve direct and easy industrial drive and EnDat2.2 and BiSS-C absolute position sensors connection. By using a portion of the precision analog circuitry also on the chip, these same devices can further decode the resolver signal and simulate the angular information from the SIN/COS sensor.
The F28379 MCU is the first commercial microcontroller to offer wide range of sensor support, flexibility, scalability and ruggedness, making the need for custom FPGA support a sneak peek. Solutions for these 4 sensors and incremental sensors are available free of charge as part of the controlSUITETM software suite.
The C2000 MCU team is launching the new C2000 Delfino TMS320F28379S and TMS320F28379D MCUs and the DesignDRIVE Location Manager for the first time at the 2015 SPS IPC Drives Show. For more information, please visit TI booth (Hall 6, Booth 441).
