0 : Normal
1 : Error
• If the parameter type or the parameter No. is outside the range, returns No. error.
•
Parameter value is sign-extended to 32 bits and returned.

bit7 6
0 : Normal Data Error
1 : Error
• If the parameter type or the parameter No. is outside the range, returns No. error.
• This command change parameters only temporarily. If you want to write into EEPROM, execute the parameter writing
to EEPROM (mode = 2).
• 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.
• Parameter value should be sign-extended to 32 bits before being transmitted.

bit7 6
0 : Normal Data Error
1 : Error
• 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.
