Siemens 6SN1145-1AA01-0AA2 Overview

The 6SN11451AA010AA2 unit is an infeed module manufactured by Siemens as a part of the SIMODRIVE 611 drive configuration. The infeed modules serve to link the drive group to the power supply line. 

The infeed/regenerative feedback module (I/R) and unregulated infeed (UI) modules input power into the DC link, while also supplying electric power supply to the connected modules along with the monitoring module. Overload protection is not provided by the infeed modules, it must be ensured through proper configuration and current values set in the control boards.

For the unregulated infeed module, the drive energy from a braking motor is injected into the DC link.  The energy is converted into heat in the braking resistor which is then dissipated to the environment. The braking resistor may be integrated or mounted.  Required additional engineering of the system may include the use of a pulse resistor module (PR units). 

There are a couple of applications for use of the infeed module. The first beneficial application for the infeed module is working with machines that have few braking cycles or short braking cycles and low braking energy. The second use for the infeed is for drive groups with limited dynamic demands. This is particularly true for the main spindle drive.

The step-up converter, which has a hertz rating of 7 kHz, is comprised of the I/R module and the HF/HFD commutating reactors and is used for controlling the DC link voltage.  The step-up converter is also used for enabling regenerative feedback.

Which applications can I expect to work with the I/R module and the HF/HFD? There are three applications associated with the I/R module and the HF/HFD modules. The first use is with machines in an environment of high-dynamic requirements placed on the drive. The second use is with machines that include frequent braking cycles and high braking energy.

One note about the HFD line reactor: In order for the I/R module to function correctly, an HFD line reactor is prescribed. The reason being this is cyclically short-circuited for the step-up controller and the voltage control to operate properly.

The monitoring module incorporates a complete electronic power supply for the equipment bus and the central monitoring functions for a drive group that is separate. Normal power is supplied from the line supply, 3–ph. 400 to 480 V AC.  In a case of power loss, an emergency reaction occurs so there is an option to connect the power supply directly in parallel to the DC link.  The monitoring module is necessary when a higher number of drive modules are present and they exceed the power supply of the connected electronics of the infeed module, either I/R or I/U. This allows the various groups of drive modules to inhibit multiple cabinets or tiers.

How are these infeed modules arranged within the Simodrive 611 drive system? Within the drive group, the infeed module is the first module in the group on the left.  The mounted surface for the line supply infeed is I panels through a low-resistance connection. This applies to the drive modules, reactors, and line filters. 

Siemens 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 Motors from other manufacturers such as FANUC and Yaskawa.
