Siemens SINAMICS G130 Inverter

The Siemens Sinamics G130 inverter is a high-performance inverter designed to meet the needs of industrial motor control in applications requiring high precision, safety and durability. With operating power from 75 kW to 800 kW, the SINAMICS G130 is the ideal solution for industrial applications such as manufacturing, material handling, and large fan and pump systems.

Outstanding functions of the Siemens Sinamics G130 inverter

Integrated safety functions (Safety Integrated)

The Siemens Sinamics G130 inverter meets the EN 60204-1 safety standard, specifically, the product is equipped with functions such as:

• Safe Torque Off (STO): This function helps the inverter stop supplying energy to create torque, thereby preventing the motor from restarting unintentionally.
• Safe Stop 1 (SS1): This function is especially useful for applications with heavy loads or requiring emergency deceleration, replacing expensive and wear-prone mechanical brakes. SS1 supports motor braking via OFF 3 and automatically activates Safe Torque Off mode after the set safety delay has elapsed.

Power Unit Protection

The Siemens Sinamics G130 inverter provides some features to provide comprehensive system protection, including:

• Ground fault monitoring: This function detects ground faults at the output by monitoring the total current and automatically disconnects the circuit in the event of a fault.
• Electronic short circuit protection: When a short circuit occurs at the inverter outputs, in the motor cable or motor terminal box, the inverter will automatically disconnect and give a fault alarm to protect the system.
• Overheat protection: The system will issue a warning when the temperature exceeds the allowable threshold. If the temperature continues to rise, the inverter can automatically disconnect or reduce the pulse frequency and output current to reduce the heat load. When the fault is resolved (such as improved ventilation), the system will automatically restore the original settings.

Support for communication with high-level controllers

Siemens Sinamics G130 inverter supports a variety of communication protocols: PROFINET, and CANopen to connect seamlessly with other automation systems. By using the CU320 control unit, expansion modules such as TM31, TB30 and through analogue or digital signals.

Open and closed loop control functions

The Siemens Sinamics G130 inverter provides precise control with high-performance thanks to its high-quality vector control mode. Typical control modes include speed and current control, as well as motor and inverter protection.

Software and protection functions

The Siemens Sinamics G130 inverter allows the user to input preset value data both internally and externally:

• Internally as fixed preset values ​​or motor potentiometer-type regulators or jog values.
• Externally via communication interface or analogue input of the customer terminal block.

The G130 also has many other functions that provide comprehensive motor and inverter protection:

• Automatic motor recognition function, allowing quick and simple start-up and optimization of inverter control.
• Equipped with a ramp function generator, allowing separate adjustment of acceleration and deceleration times and adjustable in low and high-speed ranges, improving control response and preventing mechanical overloads.
• The VDC max controller automatically prevents overvoltages in the DC circuit if the deceleration ramp is set too short.
• The dynamic buffer (KIP) compensates for voltage loss within the allowable limits thanks to the dynamic energy of the inverter system.
• The auto-restart feature allows the inverter to restart after the power is restored after a fault and accelerate to the current preset speed value.
• The fly-start feature, allows the inverter to be connected to a rotating motor without interruption.
• The technology controller allows simple control functions such as level control or volume flow.
• The free function blocks on the inverter allow the user to program the logic and arithmetic functions of the SINAMICS G130 control.
• The DCC inverter control diagram makes it easy for the user to configure procedural functions for the SINAMICS G130.
• The block library contains a wide range of control, arithmetic and logic blocks.
• I²t detection for motor protection
• Monitoring and monitoring of the motor temperature via KTY84 or PTC temperature sensors.
• Detects motor jam and shuts down to protect motor from overheating.

Applications of Siemens Sinamics G130 inverter

With the outstanding features mentioned, the Siemens SINAMICS G130 inverter is widely used in industries that require precise and flexible control of motors. Specifically:

• Material handling systems: Control of conveyors, cranes and crushers.
• High-capacity pumps and fans: In HVAC systems, water supply and waste treatment.
• Automatic production lines: Applications in manufacturing plants, food processing, and heavy industry.

With its durable design, high protection capabilities and control flexibility, SINAMICS G130 is a reliable choice for businesses that want to optimize performance and safety in industrial motor control systems.
