• If the parameter No. is not within the range of 0 x 00 to 0 x 7F, No. error will be returned.
• This command change parameters only temporarily. If you want to write into EEPROM, execute the parameter writing
to EEPROM (mode = 4).
• Set up parameters not in use to 0 without fail, or it leads to data error. Data error also occurs when the parameter
value exceeds the setup range.
• If the parameter No. is not within the range of 0 x 00 to 0 x 7F, No. error will be returned.

Transmission data
• Writes the preset parameters to EEPROM.
• Transmission data will be returned after EEPROM writing completes. It may take max. 5sec for EEPROM writing
(when all parameters have been changed.)
• Data error will occur when writing fails.
• When under-voltage occurs, error code of control LV will be returned instead of executing writing.
