Each node on a CANopen network must have a unique Node ID. Valid ranges for the Node ID
are 0x01 through 0x7F (1~127). Node ID 0x00 is reserved in accordance with CiA301. The Node
ID is selected using rotary switches and software; one sixteen position switch set the lower four
bits (0~F) of node ID, while upper three bits of node ID are configured by Step-Servo Quick Tuner
software. Each time when Node ID is changed, a power cycle is required before the new Node ID
is valid.
Please refer to the CANopen manual for more information.
S2 used to set the CANopen baud rate, SW1, SW2 and SW3 are used to set the baud rate. SW4
is used to set the terminal resistor.
