This reference design uses a single TI C2000™ F28P65 microcontroller for industrial Ethernet motor drives with six-axis control. The design uses a printed circuit board (PCB) with less than 42cm2 to drive a 6 degree of freedom (DoF) humanoid robot hand. The design demonstrates a small form factor and integrated platform. This integrated platform leverages six DRV8376 three-phase motor drivers with integrated current sensing and FETs as the power stage. The platform includes real-time motor control and industrial Ethernet communication using the F28P65 device with two 32-bit C28x Digital Signal Processor (DSP) Central Processing Units (CPU) and one Control Law Accelerator (CLA) CPU, all running at 200MHz.
Features
- Compact design with highly integrated circuits (IC) facilitates a PCB size less than 42cm2
- Single real-time microcontroller (MCU) with two CPUs to control six independent closed-loop field-oriented control (FOC) for current, velocity, and position
- High-efficiency current monitoring and small form factor of DRV8376 with integrated low-side current-sense amplifier and integrated field-effect transistors (FET)
- Flexible communication interface option for chip-to-chip communication, for example, fast serial interface (FSI), universal asynchronous receiver-transmitter (UART), and controller area network with flexible data-rate (CAN-FD)
