VFD communication over Half-Duplex RS485
Posted: Wed Dec 29, 2021 12:20 pm
Three-phase squirrel-cage induction motors with Variable Frequency Drives (VFD) are the backbone of the industry. Today we open-sourced both the VFD FreePort Protocol Arduino Library (https://github.com/PR-DC/PRDC_FreePort) and Half-Duplex RS485 communication Library for Arduino_Core_STM32 (https://github.com/PR-DC/PRDC_RS485HD_STM32). These libraries make it possible to communicate with VFD using serial communication over RS485 in order to control and monitor its state
