Setting Node ID and baud rate
SSDC drives have one rotary switch and one piano switch to set the Node ID, baud rate and terminal resistor.
2.4.1
RS-485 Node ID and baud rate settings -R type
Set drive’s RS-485 Node ID by rotary switch S1, Set drive’s RS-485 baud rate and terminal resistor by piano switch S2
S1 is used to set drive’s RS-485 address, and th range is 0~F (0~15 in decimal). If you want the RS-485 Node ID range to
10~1F(16~31 in decimal), you need to configure it in
StepSERVO Quick Tuner
software.
