6SL3130-7TE31-2AA3 SINAMICS S120 Active Line Module 120kW 200A

The 6SL3130-7TE31-2AA3 is a SINAMICS S120 Active Line Module designed to supply a regulated DC link for high-power modular drive systems.

It converts a three-phase 380–480 V AC mains supply into a controlled 600 V DC output with a rated current of 200 A and a power rating of 120 kW.

Unlike a Basic Line Module, the 6SL3130-7TE31-2AA3 uses active line-side power electronics to control energy transfer between the mains supply and the shared DC link.

This bidirectional operating capability allows braking energy produced by connected motors to flow back through the DC link and be returned to the electrical supply when the complete system is correctly configured.

The 120 kW rating makes this module suitable for large multi-axis machines, high-current spindle systems and production equipment with substantial simultaneous power demand.

Its Booksize construction enables side-by-side installation with compatible Control Units, Single Motor Modules and Double Motor Modules in a centralized drive cabinet.

• Heavy production machinery

120 kW High-Power Infeed

The 6SL3130-7TE31-2AA3 provides up to 120 kW of line-side power for a modular drive group.

This power class is suitable for installations with:

• Multiple high-current motor axes
• Large main spindle drives
• High simultaneous power demand
• Frequent acceleration cycles
• Heavy mechanical loads
• Continuous industrial production

The correct module size must be selected according to the combined DC-link load and operating duty of all connected Motor Modules.

200 A DC-Link Supply

The module provides a rated DC output current of 200 A.

The shared DC link may supply:

• Single Motor Modules
• Double Motor Modules
• Servo axes
• Spindle axes
• Auxiliary motor groups
• Other compatible S120 components

The module does not directly control an individual motor. Motor control remains the function of the connected Motor Modules and Control Unit.

Regenerative Energy Feedback

During motor deceleration, mechanical energy can be converted into electrical energy and transferred back to the common DC link.

With a correctly configured Active Line Module system, this energy can be returned to the mains supply instead of being dissipated entirely through braking resistors.

Possible benefits include:

• Reduced braking-resistor loading
• Lower heat generation in the cabinet
• Reuse of braking energy
• Improved efficiency in cyclic machines
• Better energy management in multi-axis systems

Actual regenerative performance depends on the Active Interface Module, mains conditions, system parameters and complete electrical design.

Regulated DC-Link Operation

The Active Line Module actively controls the DC-link voltage rather than relying only on a diode rectifier.

This supports:

• Stable DC-link supply
• Bidirectional power transfer
• Controlled mains current
• Reliable operation during acceleration and braking
• Improved coordination of multiple drive axes

The regulated DC-link function is a major difference between this module and Basic or Smart Line Module configurations.

Active Interface Module Requirement

The 6SL3130-7TE31-2AA3 is normally used with the appropriate Active Interface Module.

The interface module may include:

• Line-side filtering
• Precharging components
• Mains-current conditioning components
• Protection and connection hardware

The correct Active Interface Module must be selected according to the Active Line Module rating and system documentation.

Active Line Module vs Basic Line Module

Active Line Module

Uses active line-side power electronics.

Provides a regulated DC link.

Supports bidirectional energy flow.

Can return braking energy to the mains.

Basic Line Module

Uses a diode-based rectifier supply.

Provides a non-regulated DC link.

Power normally flows from the mains to the drive.

Does not independently return braking energy to the mains.

These products should not be treated as interchangeable line supplies.

Active Line Module vs Smart Line Module

Active Line Module

Provides controlled mains current and regulated DC-link operation.

Designed for demanding regenerative applications.

Smart Line Module

Provides a simpler DC-link supply architecture.

May support energy feedback depending on the system version, but does not offer the same active mains-current control.

The original machine design must be checked before changing the Line Module type.

DRIVE-CLiQ Communication

The included DRIVE-CLiQ cable connects the Active Line Module with compatible control-system components.

Typical communication functions include:

• Automatic module identification
• Operating-status communication
• Parameter exchange
• Fault and warning diagnostics
• Temperature monitoring
• System topology detection

System Integration

A typical operating system may include:

• Main disconnect
• Protective devices
• Active Interface Module
• Active Line Module
• Shared DC link
• CU320-2 Control Unit
• Single Motor Modules
• Double Motor Modules
• Servo or spindle motors
• DRIVE-CLiQ connections

The complete line-side design must follow the approved system configuration.

Booksize Construction

The Booksize housing is designed for modular control-cabinet installation.

Installation benefits include:

• Side-by-side component arrangement
• Shared DC-link busbars
• Organized multi-axis architecture
• Reduced internal power wiring
• Easier expansion of the drive group
• Centralized line-side power supply

Because this is a 120 kW module, cabinet airflow, mechanical support and installation clearance must be carefully verified.

Internal Air Cooling

The 6SL3130-7TE31-2AA3 uses internal air cooling.

Reliable operation requires:

• Correct vertical installation
• Clear ventilation paths
• Adequate cabinet airflow
• Suitable ambient temperature
• Clean cooling channels
• Correct installation spacing
• Regular inspection of cooling components

Restricted airflow may cause thermal faults or output derating.
