Siemens 6AU1445-2AD00-0AA0 Overview

The 6AU1445-2AD00-0AA0 is a high-performance SIMOTION Drive-based Control Unit D445-2 DP/PN, offering programmable motion control capabilities. Manufactured by Siemens, this versatile control unit provides a range of interfaces and features for efficient and precise control of multiple axes in industrial automation systems. 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 HMIs from other manufacturers such as FANUC and Yaskawa.


As part of the SIMOTION product brand, the 6AU1445-2AD00-0AA0 is designed to deliver exceptional performance in motion control applications. It belongs to the high-performance class of motion control systems, enabling advanced and complex control tasks to be executed with precision.


The control unit supports a multiple-axis system, allowing it to handle up to 64 axes simultaneously. This makes it suitable for applications that require control over a large number of motion axes.
With a minimum PROFIBUS cycle clock of 1 ms, PROFINET send cycle clock of 0.25 ms, interpolator cycle clock of 0.25 ms, and servo cycle clock of 0.25 ms, the control unit ensures rapid and synchronized communication between the connected devices. The note specifies that a 0.25 ms cycle clock is achievable specifically for SERVO or SERVO-FAST applications.
The 6AU1445-2AD00-0AA0 features integrated drive control capabilities, supporting various control modes based on the SINAMICS S120 CU320-2 firmware version V4.x. It can control up to 6 servo axes, 6 vector axes, or 12 V/f (Voltage/frequency) axes. This flexibility allows for the implementation of different control strategies to suit specific application requirements.


In terms of memory, the control unit has 160 Mbyte of RAM (work memory) for executing control programs and storing data. Additionally, it provides an additional 20 Mbyte of RAM for Java applications, 56 Mbyte of RAM disk (load memory), 512 kbyte of retentive memory, and 300 Mbyte of persistent memory for user data stored on a CompactFlash (CF) card.
The 6AU1445-2AD00-0AA0 offers a variety of communication interfaces to facilitate connectivity and integration within industrial networks. It includes 6 DRIVE-CLiQ interfaces, 2 USB interfaces, 2 Industrial Ethernet interfaces, and 2 PROFIBUS interfaces. The note highlights that the PROFIBUS interfaces can be configured as masters or slaves. Additionally, the control unit provides 1 PROFINET interface with 3 ports onboard and the option to add 4 additional ports via the CBE30-2 module. The PROFINET functionality includes support for PROFINET IO with IRT (Isochronous Real-Time) and RT (Real-Time) and media redundancy protocols (MRP and MRPD).


The control unit comes equipped with a double fan/battery module, ensuring proper cooling and uninterrupted operation during power outages. It operates with a rated DC supply voltage of 24 V, with a minimum of 20.4 V and a maximum of 28.8 V. The typical consumed current is 1,900 mA, and the power loss is approximately 46 W under typical operating conditions.
Regarding environmental specifications, the control unit can be stored within a temperature range of -25 to +55 °C and transported within a range of -40 to +70 °C. During operation, it is designed to operate within a temperature range of 0 to 55 °C. The control unit is rated for an ambient humidity range of 5 to 95% without condensation.


In terms of physical dimensions, the 6AU1445-2AD00-0AA0 has a height of 380 mm, a width of 50 mm, and a depth of 270 mm (230 mm when the spacer is removed). It weighs approximately 4,300 g.
The control unit features 12 digital inputs and 16 digital inputs/outputs (I/Os) that can be parameterized for various functionalities such as digital input, digital output, probe input, or cam output. The digital inputs operate with a rated voltage of 24 V and have electrical isolation in groups of 6. The digital I/Os can also function as cam outputs with a reproducibility of 10 µs and a resolution of 1 µs.
The 6AU1445-2AD00-0AA0 control unit offers reliable performance, extensive communication capabilities, and ample memory capacity, making it a suitable choice for demanding motion control applications in industrial automation. It has obtained various certifications, including cULus (USA and Canada), RCM (Australia), KCC (Korea), and EAC (Russia, Belarus, and Kazakhstan), ensuring compliance with relevant safety and quality standards.
