What to do if my YASKAWA PROFINET V1000 displays a Serial communication transmission error?

A serial communication transmission error on your YASKAWA Controller may be due to: * Faulty communication wiring: Check for and correct any wiring errors. * Short circuit or communications disconnection: Check disconnected cables and short circuits and repair them. * Programming error on the master side: Check communications at start-up and correct programming errors. * Damaged communication circuitry: Perform a self-diagnostics check. If the problem continues, replace either the control board or the entire drive. * Termination resistor of the MEMOBUS/ Modbus communications is not enabled: Set DIP switch S2 to the ON position to enable the termination resistor on a drive located at the end of a network line.
