How to fix Option Communication Error on YASKAWA A1000?
- D
  Dave SalazarAug 20, 2025
  If you encounter an Option Communication Error with your YASKAWA Controller, first check for faulty wiring if the connection is broken or the master controller stopped communicating. If wiring isn't the issue and the fault persists, the option may be damaged and require replacement. Ensure the option is properly connected to the drive by reinstalling it. Also, consider checking options to minimize the effects of noise if a data error occurred.

Why does my YASKAWA A1000 have a MEMOBUS/Modbus Communication Error?
- J
  Julie HarrisAug 21, 2025
  If you're experiencing a MEMOBUS/Modbus Communication Error with your YASKAWA Controller, consider these steps: First, check options available to minimize the effects of noise if a data error occurred. Next, verify the H5 parameter settings and the protocol setting in the controller to ensure communication protocol compatibility. Also, if the CE detection time is too short, change the software settings in the PLC.

What to do if YASKAWA Controller shows a Braking Transistor Overload Fault?
- R
  Ronnie NavarroSep 7, 2025
  If the YASKAWA Controller's braking transistor reaches its overload level, select the proper braking resistor. Ensure the correct braking resistor is installed, fitting the drive braking transistor specification. If the use rate is high, switch to a CDBR type braking unit. If the braking transistor inside the drive is faulty, consider replacing the drive.
