memory. In this operation parameter writing is not executed and the data in EEPROM
parameter area will be read into the memory again when power on. If user want to
permanently use the parameters in EEPROM backup area, another parameter write
operation is needed.
z EE－dEF: default recovery It means to read all default values (factory set values) of
parameters into memory and write them into EEPROM parameter area to be used when
power on again. Perform this operation to restore all parameters to their factory set values
if these parameters are disordered by user causing the system abnormal running.
Because the different AC servo drive unit model corresponds to different parameter default
values, ensure that the AC servo drive unit model is right (parameter No.1) when
performing this default recovery operation.
