INTERNAL ELECTRICAL INTERFACE
Introduction
The AUBO robot I series standard control box provides a variety of electrical interfaces to connect the
external equipments and tools. Users can easily use these interfaces.
The electrical interface of the control box is divided into: safety I/O and general I/O. The AUBO interface
board has 16 general digital input interfaces, 16 general digital output interfaces, 4 pairs of analog voltage
input interfaces, 2 pairs of analog voltage output interfaces and 2 pairs of analog current output interface.
The electrical error is about ±1%.
IO Specification
All AUBO robot IOs are set to NPN mode, which means low voltage level effective. When an User IO is
set to “Effective” or “High” on the teach pendant, the actual voltage level at the IO output is low.
Note Open circuit protection is set in each IO. Therefore, whenever an IO is not connected in a closed
circuit, its output voltage is going to remain at high even if the IO is set to “Effective” by script or by teach
pendant.
For digital IO outputs, the method to check the IO status is to measure the resistance between DO and 0V.
When the DO is set to “Effective” or “High”, the resistance goes to approximately 0Ω, otherwise the
resistance is about 12KΩ.
Electrical warnings and cautions
The following warnings and cautions must be observed when a robot and control box application is
designed and installed. The warnings and cautions also apply for service work.
Never connect safety signals to a PLC which does not fulfill the requirements of a
correct safety level. Failure to follow this warning could result in serious injury or
death due to the failure of the safety stop function
1.
Make sure that all non-waterproof equipment remains dry. If water comes inside the
product, turn off all the power switches and then contact your supplier.
2.
Use original cables supplied with the robot only. Do not use the robot for
applications where the cables will be subjected to bent. Contact your supplier if
longer or flexible cables are needed.
3.
All mentioned GND connections are only for powering and transimitting signals.
For Protective Earth (PE) use the screw connections marked with the earth symbols
inside the control box. The grounding conductor shall have at least the current rating
