Deciphering the Siemens Sinamics G120c Simple Wiring Diagram
The Siemens Sinamics G120c Simple Wiring Diagram is essentially a visual representation of how electrical power and control signals are connected to the drive. It breaks down the intricate wiring into manageable sections, making it easier to identify the purpose of each terminal. This clarity is paramount for several reasons. For instance, it helps in correctly connecting the incoming power supply, ensuring phase rotation is accurate, and preventing damage to the drive or the connected motor. Furthermore, it guides the connection of the motor itself, specifying the correct terminals for different motor configurations.
The diagram typically illustrates several key connection areas:
- Power Input: This section details how to connect the main power supply (e.g., 3-phase AC) to the drive.
- Motor Output: Here, you'll find the connections for the three phases of the motor.
-
Control Terminals: These are vital for implementing control functions. They can be used for:
- Starting and stopping the motor.
- Setting motor speed via analog signals.
- Connecting digital inputs for external control signals.
- Connecting digital outputs to signal drive status.
- Grounding: Proper grounding is essential for safety and noise reduction, and the diagram clearly indicates these connections.
The importance of meticulously following the Siemens Sinamics G120c Simple Wiring Diagram cannot be overstated. Incorrect wiring can lead to operational failures, safety hazards, and premature equipment failure. The diagram also provides essential information on cable types, conductor sizes, and terminal assignments, all of which are critical for a robust and safe installation. For example, a simplified table often found within the documentation can quickly show terminal functions:
| Terminal Number | Function |
|---|---|
| L1, L2, L3 | Power Input (3-Phase AC) |
| U, V, W | Motor Output |
| DI1, DI2, etc. | Digital Inputs |
| AO1 | Analog Output |
