  If you're experiencing a serial communication transmission error with your YASKAWA Inverter, start by checking the communication wiring for faults, short circuits, or improper connections. Correct any wiring errors, remove ground shorts, and reconnect loose wires. Also, verify the communications at start-up and correct any programming errors on the master side. If the issue persists, perform a self-diagnostics check to see if the communication circuitry is damaged. If the fault continues after the self-diagnostics, the drive may need to be replaced.
