Siemens 6SN1145-1AA01-0AA1

The 6SN1145-1AA01-0AA1 drive is manufactured by Siemens Automation. This drive module is part of the SIMODRIVE series for the operation of AC motors. The Siemens 6SN1145-1AA01-0AA1 works within the drive system as an infeed module.  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 Motors from other manufacturers such as FANUC and Yaskawa.

Cross section10 mm connections can be connected at the infeed module for line supply.

There are two applications for this infeed module. 

The Siemens drive module 6SN11451AA010AA1 is used with machines that have few or short braking cycles, or low energy when braking. This Siemens unit is also used in drive groups that have constrained dynamic demands, especially in the main spindle drive. 

The step-up converter consists of the I/R modules and HF/HFD communicating reactors. 

For which applications is the Siemens 6SN11451AA010AA1 module used? This module is used for machines that have high dynamic considerations put on the drive. It is also used for both high braking energy and constant braking cycles. A third application for this module is the control cabinet designs that are made for low operating costs. 

If your drive group has a high number of drive modules for your system and it goes beyond the electronic power supply that the infeed module can accept, you will need a monitoring module. 

Features of the Siemens 6SN11451AA010AA1

What does an infeed module do within your system? You use the infeed module to connect the drive group to the supply line. The 6SN1145-1AA01-0AA1 is an unregulated infeed module. It works with the infeed/regenerative feedback module, or IR, and the monitoring module to provide the power to the electronics power supply for the connected modules.

Is there overload protection with the unregulated infeed module? The Siemens 6SN1145-1AA01-0AA1 unregulated infeed module does not have any comprehensive overload protection. To achieve comprehensive overload protection, the current value in the control board must be configured with the correct setting. 

When the motor brakes, heat develops from the drive energy going into the DC link. This heat happens in the braking resistors. It then goes out into the environment. You will find the braking resistors can either be integrated or mounted. Depending on your system, it may be necessary to have one or more extra pulsed resistor modules. 

How do you select the Siemens infeed module that best meets your needs within the drive system? You select the infeed module using the DC link power that the group requires. Identifying the active power requirement of all of your power modules is another important data point. There are a couple of more things to consider. The first thing to consider is the coincidence factor.  The value is settled by way of the load duty cycle or experience value. The motors will not all experience a full load simultaneously.  The second thing to think about is the power needed to charge the DC link capacitors. You will need to know the maximum permissible power. Equipped with this information, the ability to select the Siemens module that fits your automation needs is straightforward.
