Yaskawa YPHT31261-2G CPU Power Drive Motherboard

The Yaskawa YPHT31261-2G CPU Power Drive Motherboard is an industrial PCB that handles inverter control, CPU processing, and power management inside Yaskawa frequency inverters and AC drives. Built for 18.5 kW-class inverter platforms, it coordinates inverter communication and drive logic, including subsystem communication, and is installed internally within the drive system. This board supports CNC systems, conveyor systems, pumps, fans, and other heavy motor control applications in automation environments; it's commonly used for repair, retrofit, or replacement by maintenance teams and system integrators. Originating from Japan, this used, surplus, and refurbished motherboard is a legacy/discontinued component compatible with Yaskawa systems, with common replacements including YPCT31527-2A, YPCT31392-1A, and YPHT31040-1B.
