Siemens 6SN1123-1AA01-0FA1 Overview

The Power Module 6SN11231AA010FA1, manufactured by Siemens, is an essential component of the drive module used in feed or main spindle applications. It works in conjunction with the control module to provide efficient and reliable motor operation. The power module supports various types of motors, including servo motors (1FT6, 1FK6, and 1FK7), built-in torque motors (1FW6), linear motors (1FN), main spindle motors (1PH), standard induction motors, hollow shaft motors for main spindle drives (1PM), main spindle motors (1FE1), and motor spindles (2SP1). These products are manufactured in Germany and are designed for Automotive, aerospace, power generation, and electronics usage. They come with a 2-year warranty from MRO Electric. We also carry AC Drives from other manufacturers such as FANUC and Yaskawa.


For standard induction motors, the power module allows inverter pulse frequencies of 4 kHz and 8 kHz in the IM (inverter mode) operation. Additionally, it can accommodate third-party motors that meet specific requirements for sine modulation, insulation, and dV/dt resistance.

In some cases, special motors with low leakage inductance may require additional components such as a 3-arm iron core reactor or higher inverter pulse frequencies to ensure optimal performance. Motors with low leakage inductance typically have high stator frequencies or high rated currents.

The power modules are available in a wide range of 1-axis or 2-axis versions, classified based on current ratings and cooling techniques. The current values provided are normalized and serve as reference values for control units. It's important to note that output currents can be limited by the control unit being used.

To ensure a secure electrical connection, it's crucial to tighten the retaining screws of the control unit front panel after insertion. The power module comes equipped with overload protection, which prevents motors and cables from being overloaded when appropriately dimensioned. However, it's worth noting that the overload protection may not fully comply with UL508C Version 2010 requirements regarding cable protection.


The power module includes an equipment bus cable, while drive bus cables need to be ordered separately for the digital system. It's recommended to use matched, pre-assembled cables for motor connections, which can be found in the "Motors" section of the NC 60 catalog. Shield terminal plates are also available to meet EMC requirements when using shielded power cables.


In terms of operating modes, the power module supports synchronous motors (FD mode) such as servo motors, built-in torque motors, and linear motors. It also works with induction motors (MSD-IM mode) including main spindle motors and hollow shaft motors, as well as synchronous motors (MSD-SRM mode) like main spindle motors and motor spindles. Different inverter pulse frequencies and operating parameters may apply depending on the motor type and mode of operation.

The technical data for the power module, including current ratings, power losses, input voltage, efficiency, and module width, can be found in the manual. It's essential to consider derating factors and environmental conditions such as ambient temperature and installation altitude when operating the power module outside the specified values.

In summary, the Power Module 6SN11231AA010FA1 is a versatile and robust component that plays a crucial role in driving various types of motors in feed or main spindle applications. It offers reliable motor control and is designed to meet the diverse needs of industrial automation systems.
