Description

The commonly-accepted existing solution to interface Tamagawa SmartAbs full-absolute or Smart Inc encoders with a drive feedback and control system is to use a Smartceiver AU5561N1. Use of these receivers requires additional components: complexity: and costs to the system. This reference design details a compatible receiver implementation using Sitara™ AM437x processors: which have an Arm® Cortex®-A9 core and multiple instances of PRU-ICSS. This receiver implementation bypasses the requirement for additional components because a single instance of PRU-ICSS controls the Tamagawa encoder: while the ARM device and remaining PRU-ICSS resources handle the drive control: current sense: and industrial communications. This implementation allows for a cost-effective: single-chip: industrial drive and communication solution.
