Hello, I am working on a project using Twincat 3 (Beckhoff) with a Yaskawa V1000 drive. I am able to write parameters to the drive via modbus from Twincat, but unfortunately, the parameters are only saved in the drive's RAM memory. Upon power cycling, the parameters revert to their default settings. I have reviewed the manuals for Yaskawa inverters and communication protocols, but have been unsuccessful in finding a solution. Can anyone offer assistance on how to save parameters to the EEPROM memory in the drive? Thank you.
To save parameters in EEPROM memory, it is essential to set register 0900H to 0. This step, outlined in the manual, is crucial for proper functionality. However, if Terminal S2 is configured to "Enable write constant," ensure to activate this setting. Otherwise, you will not be able to write to register 0900H and save parameters to EEPROM.
From my experience with Yaskawa drives, after writing a parameter, you would normally need to set parameter A1-03 (Memory Operation Mode) and then trigger A1-04 (Storing operation) to save those parameters into the EEPROM. However, it's crucial to clear A1-03 once you're done to prevent inadvertent writing to EEPROM in the future. Always make sure to refer to your specific model's manual as this sequence could slightly vary depending on the drive version.
Hey there! I’ve worked with Yaskawa drives before. If the values revert to defaults after power cycling, it suggests that the parameters aren't being saved in the permanent memory. To keep the parameters stored even after a power cycle, you normally use a write command to the drive's EEPROM after setting your parameters. However, the exact implementation might vary, based on the specific model of the drive. Have you looked into that or tried the Yaskawa technical support for more help on the exact commands for your V1000 model?

Answer: - To save parameters to the EEPROM memory of a Yaskawa V1000 drive when using Twincat 3, you need to ensure that the parameters are written to the EEPROM instead of just the RAM memory. This involves sending the correct commands or instructions through the modbus communication from Twincat to the drive.
Answer: - The parameters revert to default settings on the Yaskawa V1000 drive after power cycling because they are currently only saved in the drive's RAM memory, which is volatile and does not retain data when power is removed. To retain the parameters, they need to be saved to the non-volatile EEPROM memory of the drive.
Answer: - You can refer to the manuals for Yaskawa inverters and communication protocols for guidance on saving parameters to the EEPROM memory of a Yaskawa V1000 drive. Additionally, seeking assistance from forums, online communities, or contacting technical support from Yaskawa or Beckhoff may provide further insights and solutions.
