Siemens 6SN1123-1AA00-0CA1 Overview

Originally manufactured in Germany, the Siemens Simodrive could be a fantastic addition to your factory automation line. This 6SN1123-1AA00-0CA1 is a power module which find itself a part of the Simodrive series. This is a crucial part of the operation of the drive as a whole, as without the power module, the commands sent by the controller will not be passed on and the operation of the drive will not continue. 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.


The Siemens 6SN1123-1AA00-0CA1is a 1 Axis, 50 A, power module fitted out with an internal cooling system, and a motor rated current of 1FT5=25 A, 1FT6 = 18 A, 1PH = 24 A, and an induction motor equivalent to 24 A. As one part of the drive module, the power supply is integral in the overall process that will result in success operation.  Depending on the cooling method that is put into use, the power module may require additional cooling mechanisms to operate successfully and to its fullest capacity. 

At a depth of 80 mm, width of 50 mm, and height of 480, this Siemens Simodrive 611 is a great product, either to replace an existing Simodrive 611, or in order to have an extra on hand in case of a malfunction of any current 611 Simodrives you have in use. Either way, this product is another example of a part of a greater system that is designed to run seamlessly with all the right components.

The power module performs a fundamentally necessary function: bringing to the motor and control boards it is connected to, the energy necessary.  This is also at the heart of how a particular power module is chosen verses another: the power module is chosen based on the control boards. The PE connecting screws are a great asset as they ground the power module and the power module is not safe to use unless it is successfully installed to a surface that will not be a strong conductor.


The power module used must be chosen accordingly, to align with the corresponding motor and requirement for the drive that will be utilized. In setting up the physical system, the infeed module comes first before the largest power module, and the other power modules follow in order of size/power rating. The capacitor units are required to come after the power modules, at the end of the line-up of the drive.  This basic set up, along with many other instructions regarding safety, set up, maintenance, warning signs, general function, and overall knowledge are contained in the PDF manual on this product page.

According to the 6SN1123-1AA00-0CA1 manual, if you have a Simodrive 611 that currently utilizes a 6SN1123-1AA00-0CA1, and you are in need of a replacement, it is fundamental to continued use of the Simodrive that the replacement power module be the same type as the existing one. If the replacement power module or motor is not the same type, the designated limits could end up with varying results and this could damage the Siemens system in use.
