Drive Communication Port 
   
There are two ways of wiring: 
1.  Connect with RJ45 connector. 
2.  Use terminal SG+, SG- and SGND. 
 
Terminal Resistor Setting 
When using Modbus communication, the terminal equipment needs to be connected to a terminal 
resistor. You can use the built-in terminal resistor on the control board by switching the dip switch to 
the bottom (120).
