  If your Sumitomo Inverter displays a Serial Communication Transmission Error, the issue might stem from: * Faulty communication wiring, a short circuit, or improper connection. Check for wiring errors, correct the wiring, remove and ground shorts, and reconnect loose wires. * A programming error on the master side. Check communications at start-up and correct any programming errors. * Damaged communication circuitry. Perform a self-diagnostics check and replace the drive if the fault persists.

Why does my Sumitomo HF-520 show a CC-Link Option Communication Error?
- B
  Billy ClarkNov 15, 2025
  A CC-Link Option Communication Error on your Sumitomo Inverter can occur for several reasons: * The master controller (PLC) might have stopped communicating. In this case, check for faulty wiring and correct any wiring problems. * The communication cable may not be properly connected. * A data error might have occurred due to noise. To address this, check the options available to minimize noise, take steps to counteract noise in the control circuit wiring, main circuit lines, and ground wiring. If a magnetic contactor is identified as a source of noise, install a surge absorber to the contactor coil. Use Sumitomo-recommended cables or shielded lines, grounding the shield on both the PLC and CC-Link Option sides. * The CC-Link Option itself could be damaged. If wiring is not the is...
