On the KUKA control cabinet, the distinction of lines is mainly achieved through color, labels, functions, and positions. Here are some specific differentiation methods:
1、 Color differentiation
The wires inside the control cabinet usually use certain color standards to distinguish different types of circuits,
which may vary depending on the manufacturer or specific application, but usually follow some basic rules:
Transmission lines: Bright colors such as red, brown, and yellow are commonly used to identify transmission lines, which help quickly identify power lines and distinguish different voltage levels.
Control signal lines: Blue, yellow green, and other colors are commonly used for control signal lines, which are responsible for transmitting control signals such as digital input/output and analog input/output.
Neutral wire (neutral wire): Colors such as black and white are commonly used to identify neutral wires (neutral wires), which play a role in current backflow in circuits.
2、 Label differentiation
In the KUKA control cabinet, each circuit usually has a label with the circuit number, functional description, or other relevant information.
These labels help maintenance personnel quickly identify the functionality and connection location of the circuit.
3、 Functional differentiation
According to the function of the circuit, the circuits in the KUKA control cabinet can be divided into the following categories:
Power cord: Power cords are typically used to connect control cabinets to external power sources, including live wires (L), neutral wires (N), and ground wires (PE). These circuits are usually connected by specialized wiring terminals or sockets in the control cabinet.
Digital input/output line: The digital input line is used to receive signals from external switch sensors, such as buttons, limit switches, etc; The digital output line is used to control external devices such as relays, solenoid valves, etc.
These lines are usually connected by dedicated digital input/output cards in the control cabinet.
Analog input/output lines: Analog input lines are used to receive signals from external analog sensors, such as temperature sensors, pressure sensors, etc;
The analog output line is used to control external analog devices, such as motor speed controllers. These circuits are usually connected by dedicated analog input/output boards in the control cabinet.
4、 Location differentiation
In the KUKA control cabinet, different types of circuits are usually arranged in different locations or areas for maintenance and management purposes.
For example, power cords may be arranged at the bottom or side of the control cabinet to facilitate connection with external power sources; Digital input/output lines and analog input/output lines may be arranged in the middle or upper part of the control cabinet to facilitate connection with internal control circuits.
