FAQ What is the main difference between the SINAMICS DCM 6RA80 and the older SIMOREG 6RA70 series?The SINAMICS DCM 6RA80 series offers higher computing power, enhanced functionality, and seamless integration into Siemens’ TIA Portal (Totally Integrated Automation). It also features a more compact design for some power ratings compared to its 6RA70 predecessor. Is this a 2-quadrant or 4-quadrant drive, and what does that mean for my application?This is a 4-quadrant drive. This means it can control the motor’s speed and torque in both forward and reverse directions, as well as brake the motor by returning energy to the power supply (regeneration). This is essential for applications with frequent braking cycles or overhauling loads. Does this unit require an external CUD (Control Unit) or is it integrated?The SINAMICS DC MASTER features an integrated Control Unit (CUD). The standard CUD provides all necessary control and communication functions, though optional advanced CUDs or expansion modules can be added for more complex tasks.
