How to Save Parameters to Yaskawa V1000 Drives EEPROM with Twincat 3

Question:

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.

Frequently Asked Questions (FAQ)

FAQ: 1. How can I save parameters to the EEPROM memory of a Yaskawa V1000 drive when using Twincat 3?

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.

FAQ: 2. Why do the parameters revert to default settings on the Yaskawa V1000 drive after power cycling?

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.

FAQ: 3. Where can I find information on saving parameters to the EEPROM memory of a Yaskawa V1000 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.
