This reference design shows how AM243x is able to support a fully-integrated real-time servo motor drive control and industrial communication path. This path extends from receiving EtherCAT® CiA402 target commands for velocity, to performing closed-loop FOC velocity control of dual connected motors, to passing the actual velocity values back up to the EtherCAT PLC.
Features
- Single-chip, dual-servo motor control
- BOOST-XL TI BoosterPack™ plug-in module design - 80 digital and analog I/O compatible with AM2x LaunchPad™ development kits
- Two axes of 3-phase BLDC motor drive with the DRV8316R 24V, 8A monolithic gate drive and amplifier bridges
- Two axes (six channels) of 3-phase current feedback through AMC1035D sigma-delta modulator and INA241A current sense path
- Two axes of RS-485 based absolute encoder feedback supporting multiple industrial encoder standards
