Overview Manuals Specifications Application Communication Safety and Compliance

Features:

  • Single-axis SIMODRIVE 611 power module in the 300 A power-module class.
  • Rated for 100 A feed-axis motors and 120 A main-spindle motors.
  • Internal-cooling configuration requiring an add-on fan or an engineered hose-cooling arrangement.
The Siemens 6SN1123-1AA00-0JA1 is the specified spare-part configuration for a high-current, single-axis SIMODRIVE 611 drive module.

A complete drive module is formed by inserting a compatible control unit into the power module, enabling operation as a controlled feed-axis or main-spindle drive.

Selection must follow the Siemens engineering tables, with the control unit, motor data, infeed capacity and cooling arrangement checked as one complete drive configuration.

The Siemens 6SN1123-1AA00-0JA1 is classified as PM410 Product Cancellation by the manufacturer (OEM).

  • Controls high-current feed axes in machine tools equipped with modular SIMODRIVE 611 drive systems.
  • Supplies the power stage for main-spindle operation in compatible CNC machinery.
  • Supports modular drive groups used in complex machining centers and automatic lathes.
  • The supplied equipment-bus cable connects the module within the SIMODRIVE 611 drive group.
  • Digital drive-bus cables are separate components and must be ordered for compatible digital control systems.
  • Command and feedback processing is handled by the inserted control unit rather than by an independent power-module fieldbus interface.
  • The control-unit retaining screws must be tightened to establish a reliable electrical connection with the module housing.
  • The module must be installed on a grounded, low-resistance conductive surface with the protective conductor correctly connected.
  • If a motor contactor is installed, Siemens requires the power circuit to be switched only while current-free.
Description
Siemens 6SN1123-1AA00-0JA1 converts electrical energy from a modular SIMODRIVE 611 drive group into controlled three-phase power for the connected motor. A compatible plug-in control unit processes the drive commands and regulates the required motor response. This separation of control electronics and power hardware supports the modular architecture used throughout the SIMODRIVE 611 system.

The module is intended for demanding motion functions in CNC machine tools, automated production machinery and industrial equipment requiring controlled feed-axis or spindle operation. Its high-output construction supports applications where accurate torque, speed and positioning performance must be maintained under substantial mechanical loads.

When Siemens 6SN1123-1AA00-0JA1 is used as a service replacement, the installed infeed module, control unit, motor data, interface hardware and cabinet cooling concept must remain compatible. Correct system matching preserves the electrical connections, control behavior and mechanical integration of the original drive configuration.

Technical notes
The 6SN1123-1AA00-0JA1 can retain hazardous DC-link voltage after shutdown. Observe the Siemens discharge waiting period and verify the voltage before removing covers or touching terminals.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Does the 300 A rating of 6SN1123-1AA00-0JA1 represent the continuous motor current?
No. Siemens identifies 6SN1123-1AA00-0JA1 as a 300 A power-module class. The official motor ratings are 100 A for feed-axis duty and 120 A for main-spindle duty.
Which motor terminals are used on Siemens 6SN1123-1AA00-0JA1?
Terminal group A1 is assigned to Axis 1. The A2 position is not assigned because 6SN1123-1AA00-0JA1 is a single-axis module.
What applications use Siemens 6SN1123-1AA00-0JA1?
Typical applications include CNC feed axes, machine-tool spindles, automated manufacturing equipment and high-output industrial motion systems built around SIMODRIVE 611 hardware.
What cooling is required for Siemens 6SN1123-1AA00-0JA1?
The official Siemens designation specifies internal cooling with an additional fan or a hose-cooling arrangement. The original cabinet airflow and cooling design must be retained when replacing the module.
Is Siemens 6SN1123-1AA00-0JA1 compatible with every SIMODRIVE 611 control card?
Compatibility must be checked against the control-unit type, motor, encoder or feedback system, infeed capacity and machine configuration. Membership in the SIMODRIVE 611 family alone does not guarantee interchangeability.
What information should be provided when requesting a quotation for 6SN1123-1AA00-0JA1?
Provide the complete order number, required quantity, acceptable condition, destination and a clear nameplate image. Details of the control unit, infeed module, motor and cooling configuration can help confirm system suitability.
