(1) Provide voltage and have the function of power distribution

                               The role of RDC in the KUKA robotic arm

(2) The decombiner (SIL2) technology is used to collect the orientation information of the eight motors for orientation feedback

(3) Obtain the real-time temperature of the motor (PTC)

(4) It also has self-temperature feedback and adds thermal electronic components

(5) Interact with the MFC-DSE function data acquisition card in the brain of the controller host

(6) On-line diagnosis of whether the circuit of the closed loop of the decombiner is aborted

(7) Evaluation of EMD or EMT, data saving, storage to EDS (Electronic Data Memory).

In addition, two FPGAs (Field Programmable Gate Arrays) can be used for safe dual-channel resolver evaluation and resolver data analysis and processing. Similar to ABB's security chain, ABB mainly relies on logic gates to complete, while KUKA is triggered by electronic components, there are some differences, FPGA is a customized circuit chip, and there are some differences with single-chip microcomputer, this is mainly based on parallel computing.

If the mission of the two FPGAs is the same, the data is compared, and then the results are checked. When the data of the two FPGAs is consistent, it communicates with the control system normally. Otherwise, EtherCAT will stop reporting errors.
