What to do if YASKAWA 1000 DC Drives show Serial Communication Transmission Error?
- DDenise SimonSep 1, 2025
If you're experiencing a Serial Communication Transmission Error with your YASKAWA DC Drive, begin by inspecting the communication wiring and terminal resistor connections for faults, short circuits, or improperly connected components. Correct any wiring errors, remove ground shorts, and reconnect any loose wires. Also, review the master-side programming for errors, particularly at start-up. If the issue persists, perform a self-diagnostics check, and if the fault continues, replace the drive, as the communication circuitry may be damaged.
