6SL3120-2TE21-0AA4 SINAMICS S120 Double Motor Module 9A Dual Axis Booksize

The 6SL3120-2TE21-0AA4 is a SINAMICS S120 Double Motor Module designed to supply and control two motor axes within a modular motion system.

This module provides two independent 9 A output channels from a single compact Booksize housing. It is suitable for machines that require dual-axis control but do not need the higher 18 A output offered by larger double motor modules.

The 600 V DC input is converted into controlled three-phase 400 V AC output for compatible motor axes. Optimized pulse patterns support stable motor-current control and responsive motion performance.

Extended Safety Integrated functions are supported when the module is combined with the correct control unit, firmware and machine safety configuration.

The included DRIVE-CLiQ cable supports communication between compatible drive components and simplifies system identification, parameter exchange and diagnostics.

The 6SL3120-2TE21-0AA4 is not a complete standalone inverter. It must operate with compatible line modules, control hardware, motors and system configuration.

Key Features

• Dual 9 A motor outputs
• Two-axis motor control
• Compact Booksize construction
• 600 V DC input
• Three-phase 400 V AC output
• Internal air cooling
• Optimized pulse patterns
• Extended Safety Integrated support
• DRIVE-CLiQ cable included

Typical Applications

• Packaging machines
• CNC auxiliary axes
• Assembly equipment
• Printing machinery
• Automated production systems

Dual 9 A Output Configuration

The module provides two independent motor channels:

Axis 1

9 A

Axis 2

9 A

This configuration is suitable when two medium-current axes must be installed in limited cabinet space.

Compared with using two separate single motor modules, the dual-channel design can reduce:

• Cabinet width
• Module count
• DC-link connections
• Internal wiring
• Installation complexity

Optimized Pulse Control

The 6SL3120-2TE21-0AA4 uses optimized pulse patterns for motor-side power control.

This supports:

• Stable current regulation
• Smooth motor operation
• Controlled torque response
• Reliable axis acceleration
• Coordinated dual-axis movement

Safety Integrated Support

The module supports extended Safety Integrated functions as part of a correctly configured drive system.

The available safety functions depend on:

• Control unit
• Firmware version
• Motor feedback
• Safety licensing
• Machine configuration

Do not list a specific SIL or PL rating unless the complete installed system and function have been verified.

DRIVE-CLiQ Integration

The included DRIVE-CLiQ cable supports digital communication between compatible drive components.

Typical functions include:

• Automatic component identification
• Parameter communication
• Status monitoring
• Diagnostic data exchange
• Simplified commissioning

System Components

A complete operating system normally requires:

• Control Unit
• Line Module
• DC-link connection
• Compatible motors
• Motor feedback devices
• DRIVE-CLiQ communication
• Correct engineering software

The module cannot operate as an independent variable frequency drive.

Installation Guidelines

Disconnect the complete DC-link supply.

Wait for the DC bus to discharge.

Verify the exact order number.

Check the cabinet airflow.

Inspect DC-link and motor connections.

Connect the DRIVE-CLiQ cable correctly.

Restore the original drive parameters.

Confirm both motor assignments.

Test each axis separately.

Verify safety functions before production operation.

Installation should be performed by qualified drive-system personnel.

FAQ
