1.3 Specification

The BP-AM2BLDCSERVO is divided up into axis-1 and axis-2 component channels with a few common system components. All motor control I/O from the attached MCU are passed through the BoosterPack headers. Screw terminals are used to provide a quick attachment point for bench DC power and attaching BLDC motor drive output.

Axis-1 and axis-2 channels both include a DRV8316 BLDC 3-phase motor driver, RS-485 transceiver set for 2-wire and 4-wire absolute encoder communication, and AMC1035D based Sigma-Delta current feedback channels for each 3-phase motor driver output.

Additionally, axis-1 includes direct INA241A current sense amplifier feedback channels for MCU ADC sampling and a resolver excitation and receiver amplifier network.

The encoder RS-485 transceivers and resolver amplifier I/O are routed to Dsub15 female connectors and optional 100-mil pitch headers that are routed in line with minimal distance between them. This gives a standard connector interface as well as the flexible prototyping headers to account for different encoder and resolver pinouts.
