当一台电机进行制动时，它将电能回馈到SIMOVERT MASTERDRIVES，因而导致直流母线电压的升高。制动单元并联连接到直流母线上并将直流母线电压限制到可以接受的水平。制动单元将制动能量送至外部制动电阻上并转换成热能。制动单元上必须总接有合适的电阻。没有制动电阻，制动能量便无法转换。
通过直流母线端子，制动单元可连接至变频器或逆变器上。当直流母线电压达到一个预定限值时，制动单元自动开通以防止直流母线电压继续增长。
制动单元的运行同变频器或逆变器无关。
制动单元电子器件由直流母线电压供电。
为提高制动功率，制动单元可并联连接。
been increased. The use of PC-based control (= using a PC with an integrated PLC) is a more common solution than using standard PLC communication with a PC link. Pc-based control combines PLC with data processing on a PC with WinAC Slot 412/WinAC Slot 416.
WinAC Slot/WinAC Slot 416 integrates open-loop control and closed-loop control automation tasks, data processing, communication and visualization in a single PC. WinAC Slot/WinAC Slot 416 is based on the original Windows NT and integrates into the office world using standard interfaces. WinAC stands for Windows Automation Center.
WinAC Controlling with CPU 41x-2 PCI
WinAC Controlling is the controlling component for WinAC Slot 412/WinAC Slot 416. WinAC Controlling performs the tasks of a traditional programmable logic controller and is fully integrated into the PC. WinAC Controlling consists of either CPU 412-2 PCI or CPU 416-2 PCI. These cpus have the typical characteristics of PLC:
· Warm start (heavy start) or exact full restart (using PC expansion circuit board) as required
· Critical behavior with real-time response time
Real-time clock,
· Use battery backup data to maintain power failure (use PS expansion circuit board)
· External mount memory for storing PLC programs independent of PC hard disk
· Integrated MPI for connecting programmers to achieve technical services, for programming or for networking with other stations
· Integrated PROFIBUS-DP interface
