01Product Overview

Siemens 6SL3120-1TE21-0AA4 is the AA4 generation of the 9 A SINAMICS S120 Single Motor Module. Its data sheet documents 7.7 A base-load current, 10.0 A S6 current and 27.0 A maximum current, clearly separating it from the 18 A peak-current AA3 generation. The module uses an integrated X1 connection plug and is currently identified as a spare-part article in Siemens comparison information.

04System Integration

  • Confirm the full AA4 article number and integrated connector arrangement.
  • Verify that the original motor and mechanical system are engineered for the configured current limits.
  • Reconnect the DRIVE-CLiQ topology and retain the original Control Unit firmware baseline.
  • Keep the shielded motor cable at or below 50 m, or the unshielded cable at or below 75 m.
  • Restore and accept the extended Safety Integrated functions after hardware replacement.
  • Review connector, S6-current, airflow and project differences before evaluating the D-type 6SL3120-1TE21-0AD0.

05Applications

  • Single S120 axes requiring a 9 A rated AA4 module.
  • Dynamic servo axes using the documented 27 A maximum current within the engineered duty cycle.
  • Machine-tool and material-handling systems with integrated X1 motor connection.
  • Spare-part service for installations already validated around AA4 hardware.
  • Safety-related drives using the documented extended Safety Integrated functions.
  • Lifecycle projects comparing an AA4 spare-part strategy with D-type migration.

06FAQ

What is the maximum current for 6SL3120-1TE21-0AA4?

The official AA4 data sheet specifies 27.0 A.

How does it differ from the AA3 9 A module?

The AA3 family data gives an 18 A peak value, while AA4 is documented at 27 A and uses the later integrated connection arrangement.

What S6 current is specified?

The S6 40 percent duty current is 10.0 A.

Which motor connector is used?

Siemens identifies an integrated X1 connection plug for the AA4 module.

What safety functions are supported?

The documented Safety Integrated level is SIL 2, PL d and Category 3, subject to correct system configuration and acceptance.

What should be compared before choosing AD0?

Compare hardware generation, connector style, S6 current, airflow, firmware, project data, DRIVE-CLiQ topology and safety configuration.
