Outstanding functions on Siemens Sinamics G150 inverter cabinet
Communication and connection
Siemens SINAMICS G150 inverter supports communication with higher-level controllers via PROFIBUS interface (standard) and can optionally use PROFINET interface (K95 option) according to PROFIdrive configuration, flexible in integration into automation systems.
In addition, the product also has standard digital inputs/outputs that can be expanded with terminal modules such as TB30 or TM31, providing flexibility in configuration and suitability for diverse industrial application requirements.
Open-loop and closed-loop control functions
The Siemens SINAMICS G150 inverter integrates two inverter control modes, including:
- Open-loop vector control provides precise speed and current control while protecting the motor and inverter from load and overload problems.
- PID control: Allows basic technological control functions such as level or flow control, suitable for applications requiring closed-loop control.
Software and protection functions
The Siemens SINAMICS G150 inverter supports the user to set the setpoint by providing values directly on the inverter or via the communication interface or analogue input. The system also supports flexible adjustment of these values based on control commands from various sources.
The automatic motor recognition function on the Sinamics G150 enables quick start-up and optimizes closed-loop control, reducing setup time for drive systems.
In addition, the Sinamics G150 integrates acceleration/deceleration function generators, allowing the user to set smooth acceleration/deceleration parameters, reducing stress on mechanical components and preventing overloads during acceleration or deceleration.
DC circuit protection and stability enhancement
The Siemens SINAMICS G150 inverter is capable of automatically preventing overvoltage in the DC circuit during short deceleration times thanks to the Vdc_max controller, which protects the circuit and avoids unwanted interruptions.
At the same time, during short-term power outages, the Vdc_min control function on the Sinamics G150 will automatically utilize the kinetic energy from the rotary drive system to convert it into electrical energy, maintaining the DC voltage, preventing interruptions and keeping the system running.
Flexible and automatic start-up
The Siemens SINAMICS G150 inverter is capable of automatic restart after a temporary power failure, reducing downtime and ensuring the system quickly returns to working condition.
The Flying Restart function on the Sinamics G150 allows the inverter to connect to a rotating motor, saving restart time for large motors.
Motor and system protection function
Siemens Sinamics G150 inverter is a series of inverters with comprehensive protection functions, specifically:
- I²t protection: The software integrates a motor model, and calculates the temperature based on the current speed and load, helping to prevent thermal overload for the motor.
- Motor jam protection: When detecting a motor jam, this feature will shut down the system to avoid overheating, protecting the safety of the transmission system.
- Motor temperature assessment: Supports motor temperature protection through KTY84, PTC or Pt100 sensors, ensuring accurate and safe temperature monitoring during operation.
Control functions and technology integration
Siemens provides the Drive Control Chart (DCC) tool, which helps users configure complex control, arithmetic and logic functions with a diverse block library. In addition to helping users configure control loops easily, this tool also allows the reuse of created charts.
In addition, the Siemens Sinamics G150 inverter also has free function blocks, allowing the implementation of logic and arithmetic functions to control the inverter using the STARTER starter tool, enhancing control and customization capabilities according to needs.
Power supply protection
The Siemens Sinamics G150 inverter provides comprehensive power supply protection functions, specifically:
- Earth fault monitoring function: Helps detect earth faults at the output and automatically shuts down to protect the system.
- Electronic short circuit protection function: Helps detect short circuits at the inverter output (such as at the inverter terminals or in the motor cable) and shuts down the device with an error message.
- Overheat protection function: When the temperature is too high, the Sinamics G150 will adjust or shut down to reduce the heat load, and automatically restore the operating values when the temperature returns to normal.
Other functions
- Built-in web server: Provides information about the inverter via a web browser, accessible via HTTP or HTTPS protocol, allowing remote management.
- Essential service mode: Enhances the system’s operability in emergencies, such as fires.
- Bypass circuit: Allows the motor to operate directly from the power source or through the inverter.
Applications of the Sinamics G150 inverter
Thanks to its outstanding features in terms of control, protection and energy saving, the SINAMICS G150 is the ideal solution for industrial applications:
- Pump and fan control
- Compressor control
- Extruder and mixer
- Grinding control
