8.9 Description of 380V additional axis for drive and control integrated system
*Safety Precautions ★ Do not touch the terminal within 15 minutes after the power is cut off; otherwise, electric shock might occur
1 Select additional axis modules
The current high-power drive and control integrated 380V additional axis modules support motors with a max power of 2.9KW+0.75KW or less. Select appropriate additional axis modules according to the power requirements
2 Install servo module
2.1 The robot returns to null point and back up ghost
To avoid accidental loss of the origin or data of the robot, the robot should return to the origin and back up ghost before removing the module.
2.2 Move I/O module
After cutting off the power and standing more than 15 minutes, remove additional axis closure plates, remove I/O module, move in the heavy duty wire direction to the reserved hole on I/O module, fix I/O module with lock screws (avoid pulling the network wire or I/O module power wire during movement. First remove the wire notch cover and take out the wire).
2.3 Install additional axis modules
Insert the prepared additional axis modules between Axis3/Axis4 and I/O module, and install additional axis brake relays (DC24V).
2.4 Connect power, communication and brake wires between modules
2.4.1 Power wire interface between modules
2.4.2 Communication/brake wire interface
STO and COM need to be short-circuited by short connecting wire; DO1+~D04+ need to be connected to power 0V, and belong to the same module as brake relay or dynamic brake; the sequence of communication wires must be correct (I/O module → Axis7/Axis8 IN, J7/ Axis8 OUT → Axis3/Axis4 IN, Axis3/Axis4 OUT → Axis2/Axis5 IN, Axis2/Axis5 OUT → Axis1/Axis6 IN).

4 Additional axis setting Login permission → Settings → Product Settings → craft Setting → set "Axis Num" to 8 → power off and restart the drive and control integrated electric box
5 Motor parameter setting
5.1 Axis7 motor parameter setting
5.2 Motor mapping setting
5.3 Axis8 motor parameter setting
Refer to Axis7 motor settings and fill in the mapping address according to the actual.
6 ResetSII
After setting the motor parameters, turn the demonstrator key to the stop position → click "About" (diagnostic message) at the bottom right of the motor demonstrator screen → click "ResetSII" → Wait about 2 minutes for factory reset and then power off and restart.
Appendix: Servo Settings Reference
The following are the servo settings of BRTIRUS2550A with additional J7 & J8 (For reference only. Reduction ratio, gain and other parameters need to be adjusted according to the actual situation on the site).
