3.3.7 DIP Switches- SW1-SW8
There are 8-bit DIP switches in EM3E series drives, SW1-SW7 are used to set slave ID, SW8 is
used for self-test.
(1) SW1-SW7 for Slave ID
The slave ID (also called Site Alias) of EM3E series can be set by the following 3 methods:
2151h
2150h
DIP Switches
Slave ID
0
Read ID
0~127
Setting by DIP Switches SW1-SW7
1
Write ID
-
Setting by writing a value to 2050h
2

0
Configure to EEPROM 0004h of ESC automatically.
When 2151h=0,setting via DIP Switches SW1-SW7
Slave ID can be set a value non-zero via the SW1-SW7, activated after restarting the power
supply. The specific definition is as below:

ID = SW1*(1)+ SW2*(2)+SW3*(4)+SW4*(8)+SW5*(16)+SW6*(32)+SW7*(64)
When 2151h=1,setting via Object (2150h)
The value written in Object (2150h) is as the slave ID, activated after saving parameter and
restarting the power supply.
When 2151h=2,master configure ID to ESC(EtherCAT slave Controller)
Setting all SW1-SW7 to ON, the EtherCAT master will configure slave ID to the address of
EEPROM 0004h of ESC automatically.
