Question

I would like to control the servo system using external communication such as RS-485.
I will be writing numerical values continuously to the servo driver’s parameters, but I am concerned about the EEPRON write limit.
Is there any good solution?

Answer

Writing numerical values to the servo driver parameters through external communication will result in EEPRON writing, and the writing limit will eventually be reached.
Therefore, once you have finished setting various parameters and it is no longer necessary to retain data changes during operation during power outages, we recommend that you disable the power outage retention function.
Specifically, set P2.030 to “5”.
After setting, the set values of each parameter will not be retained during power outage. (Does not write to EEPROM)
For details, see “P2.030” in User’s Manual 8.3 Parameter Description.

Notes

The P2.030 setting will be lost when the power is turned off.
Therefore, please perform the process to set P2.030 = 5 by using external communication when starting the system.
Also, in case you need to power off and then turn on only the servo system, it is a good idea to perform the same process after an external communication error has been recovered.
