8-1-2 RS-485 Communication Related Parameters
Cn036 ID Setting
Initial Value Unit Setting Range Effective RS-485 Address
1 --
1 ~ 254 Power Re-set 0027H
Setting Description: When using the Modbus Communication Interface, each set of Drivers needs to set
different IDs in this parameter in advance; if the IDs are set repeatedly, it will result
in communication not being operated normally.

Cn037.2 RS-485 Communication Write Selection
Initial Value Unit Setting Range Effective RS-485 Address

Setting Description:
Setting Description
0
RS-485 Communication Write to
EEPROM
1
RS-485 Communication Write to
SRAM
●
The default value of Cn037.2 is 1 (RS-485 communication is written into SRAM), so the parameters
written through RS-485 will not be saved when the servo is turned off.
●
If Cn037.2 is set to 0 (RS-485 communication is written to EEPROM), although the data will be
saved after the servo is powered off, but due to the limitation of the number of writes to the EEPROM, if
it is used, there will be frequent changes to the parameters through communication, in this case, the
service life of the EEPROM inside the servo will be shortened.
