I am in the process of developing a cutting-edge control system that features a CU-320-2 DP, alongside AIM, ALM, and three motor modules. In this configuration, one motor module will function as the master while the other two will operate as slaves. We plan to establish the speed of the master motor through the PLC using Profibus communication, and subsequently, we will need to send dynamic speed ratios to the slave motors. For instance, once we set the speed for the master motor (M1), we will then modify the speed ratios for Slave 1 (S1) in relation to M1 and for Slave 2 (S2) in relation to M1 as well. My question is whether I require a CBE20 card for my CU-320-2 DP, or if I can simply connect the drives directly using the CLIQ interface. I would greatly appreciate any insights or guidance to help me get started with this system setup, as I am new to the Sinamics platform. Any help on configuring the master-slave relationship in my system would be invaluable. Thank you!

Are you familiar with the DP Master? What steps are involved in its operation? I’m skeptical about the necessity of gearing unless the application pertains to printing or a similar task. No CBE20 is required for this process.
The DP Master is an Allen-Bradley PLC equipped with a Profibus SST Card, designed to control a yarn unwinding and winding machine. This system features coordinated drives where a master drive operates alongside two slave drives that adjust their speeds dynamically based on the master drive's set speed. The master drive establishes a reference speed, while the two slave drives maintain a speed ratio in relation to the master. The winder is equipped with a sensor that gauges the yarn buildup and converts this measurement into a diameter reading. The PLC intelligently determines the dynamic speed ratios for both slave drives by referencing the master drive. All necessary programming for speed settings and ratios is already implemented, as the system currently relies on an older drive setup that is in the process of being upgraded to Sinamics technology. The gearing mechanism appears to function effectively. For instance, the Master Drive M1 is programmed to maintain a constant speed established by the PLC. Subsequently, the PLC computes the speed ratios between M1 and Slave Drive S1, transmitting these calculations to the respective drives, followed by similar computations for Slave Drive S2. I have successfully utilized gearing with servo drives from another manufacturer in the past, which yielded excellent results. However, I'm seeking guidance on the optimal approach moving forward. Do you have any recommendations? Additionally, I encountered issues accessing the link for the Sinamics S120 Gearing. Is there an alternative way to access that information?
It seems you've already figured out the coding, which aligns with how the original system operated. However, I believe implementing gearing with DCC might be excessive for this specific application—just my perspective. I recommend focusing on integrating the GSD files, fine-tuning the drives, and ensuring accurate scaling before proceeding. I'm also interested to know, what brand were the original drives? Were they Siemens or something else?
I concur that the current setup is excessive for my needs. Position control is not necessary for my application. Can you guide me on how to configure the drives as I previously outlined? The existing system features an upgraded DC drive platform with communication capabilities. It appears that it was a proprietary drive from a company that enhanced the machine. Additionally, we have acquired the DCC Editor, which provides us with the necessary functionality alongside the starter software.
It sounds like an exciting project you’re working on! As for your question, you typically don’t need a CBE20 card if you’re planning to use the CLIQ interface, as that should allow you to connect the drives directly without additional hardware. Just make sure that your firmware versions are compatible and enable the necessary settings in the CU-320-2 DP to manage the master-slave relationship. For the speed ratio adjustment, you can leverage the control parameters available in the PLC to dynamically adjust the speeds of the slave motors based on the master. It might also be beneficial to dive a bit into the documentation for the Sinamics platform; it provides a lot of useful tips and examples. Good luck with your setup!
It sounds like you’re diving into an exciting project! For the CU-320-2 DP, you have the option to connect your drives directly using the CLIQ interface, which can simplify your setup. However, if you decide to implement more advanced features or want to expand system flexibility in the future, the CBE20 card provides additional functionality like easier integration of multiple drives and improved diagnostics. Since you're new to the Sinamics platform, starting with CLIQ might be a good way to get a handle on the basics before you make any decisions about adding more complexity. Just keep in mind how you plan to manage communication between the master and slave motors once you set those speed ratios! Good luck, and feel free to ask more questions as you progress!

Answer: - The CU-320-2 DP is a control unit used in Sinamics drive systems, which allows for the management and coordination of multiple motor modules. It plays a crucial role in establishing communication and control protocols for motor operations within the system.
Answer: - In a master-slave configuration, one motor (the master) operates based on direct input, while other motors (the slaves) follow the master's lead but with specific speed or operational adjustments. This setup is used to synchronize the operations of multiple motors, ensuring they work together effectively based on the system's requirements.
Answer: - A CBE20 card is an option for adding Ethernet communication capabilities to the CU-320-2 DP. For Profibus communication, the CU-320-2 DP typically has built-in support, so a CBE20 card is generally not required unless additional Ethernet connectivity is needed.
Answer: - The CLIQ interface is designed for simple and efficient module interconnection within Sinamics systems. For
