6SL3130-6TE21-6AA4 SINAMICS S120 Smart Line Module 16kW 27A Booksize

The 6SL3130-6TE21-6AA4 is a SINAMICS S120 Smart Line Module designed to supply the common DC link of a modular multi-axis drive system.

It converts a three-phase 380–480 V AC mains input into a 600 V DC output for connected Single Motor Modules and Double Motor Modules.

With a rated power of 16 kW and a DC output-current capacity of 27 A, this model is suitable for compact machine systems with several medium-power servo or positioning axes.

The 100 mm Booksize housing allows the module to be installed alongside compatible control units and motor modules, helping reduce cabinet width and simplify the DC-link arrangement.

Unlike a Motor Module, the 6SL3130-6TE21-6AA4 does not directly power or control an individual motor. Its function is to provide line-side power for the shared DC bus.

It should also not be described as an Active Line Module. The Smart Line Module supplies a non-regulated DC link and does not provide the same active mains-current regulation as an Active Line Module.

DC-Link Supply Function

The 6SL3130-6TE21-6AA4 provides centralized DC power for compatible motor modules.

Typical power flow:

Three-phase AC mains

Smart Line Module

600 V DC link

Single or Double Motor Modules

Servo and spindle motors

This arrangement allows multiple motor axes to share one line-side supply module.

16 kW Power Class

The module is rated for a 16 kW drive-system supply and provides up to 27 A at the DC output.

The correct line module should be selected according to:

• Combined motor power
• Number of connected axes
• Simultaneous load
• Acceleration demand
• Duty cycle
• Braking-energy conditions
• Required overload capacity

100 mm Booksize Construction

The module uses a narrow 100 mm Booksize housing for cabinet installation.

Installation advantages include:

• Reduced cabinet width
• Side-by-side drive arrangement
• Short DC-link connections
• Organized component layout
• Easier system expansion

Smart Line Module Function

The Smart Line Module provides a non-regulated DC-link supply for the modular drive system.

Its primary functions include:

• AC-to-DC power conversion
• Shared DC-link supply
• Drive-system status communication
• Component diagnostics
• Modular axis power distribution

It is not a complete variable frequency drive and cannot independently control a motor.

Smart Line Module vs Basic Line Module

Smart Line Module

Compact line-side supply intended for modular systems with DRIVE-CLiQ integration and system-level monitoring.

Basic Line Module

Uses a basic diode-rectifier architecture to provide a non-regenerative DC-link supply, generally for straightforward power-feed applications.

The correct type must be selected according to the original machine configuration and line-side components.

Smart Line Module vs Active Line Module

Smart Line Module

Provides a non-regulated DC-link supply and requires the appropriate line-side system configuration.

Active Line Module

Uses active line-side power electronics to regulate the DC link and manage mains current.

These two module types should not be treated as direct substitutes.

DRIVE-CLiQ Communication

The included DRIVE-CLiQ cable supports communication with compatible system components.

Typical functions include:

• Automatic component identification
• Operating-status exchange
• Diagnostic communication
• Parameter transfer
• System topology detection

System Integration

A complete installation may include:

• Main disconnect
• Protective devices
• Line reactor
• Smart Line Module
• DC-link busbars
• Control Unit
• Single Motor Modules
• Double Motor Modules
• Servo or spindle motors

The required line reactor and protection components must match the original electrical design.

Do not select a replacement only according to appearance or the 6SL3130 prefix.

Lifecycle and Replacement Note

The 6SL3130-6TE21-6AA4 is listed as a spare-part product.

Before installing a successor model, verify:

• Mechanical dimensions
• Electrical ratings
• Firmware requirements
• Control-unit compatibility
• DC-link design
• Required line components
• DRIVE-CLiQ topology

A newer replacement should not be installed without checking the complete system configuration.

Installation Guidelines

Disconnect the incoming mains supply.

Wait for the DC link to discharge fully.

Confirm the absence of hazardous voltage.

Verify the exact order number.

Inspect the DC-link contacts.

Check mains and grounding connections.

Confirm cabinet airflow.

Connect DRIVE-CLiQ correctly.

Verify all downstream Motor Modules.

Check DC-link voltage before enabling the axes.

Installation should be completed by qualified drive-system personnel.
